Secure Android: How to Set Up SIM Card Lock? [2021]

The SIM Card Lock in android is something people don’t really bother into but it carries a significant weightage. You can really set up a screen lock easily but what you may not realize is that there is another extra layer of security that you can add i.e., the SIM Card Lock.

So what exactly is SIM Card Lock?

It is easy to say that one may assume it as some sort of alarm setting that may remove the SIM.

SIM Card Lock PIN requires a lock screen PIN, Pattern, Fingerprint or Password and a SIM Card to be active before the phone can be unlocked. It is a sort of physical two-factor authorization, which disallows hackers from tracking or misusing your SIM Card.

Let me tell you, SIM comes with a default PIN code directly from your mobile carrier. These codes vary company by company but for Sprint and T-Mobile, it is 1234, and for AT&T and Verizon, you can try 1111. Don’t worry if these codes don’t work. You can either Google about these codes or call your carrier support and ask for the codes.

So let’s dive right into securing your Android.

Setting Up SIM Card Lock in Android Phones

So for instructing on how you can set up SIM Card Lock on your android, I will be using a Samsung Galaxy S8 as a model phone.

Step 1: Go to “Settings”. You can also go on them through notifications and the top right corner gear sign.

Step 2: Tap “Lock Screen and Security”.

Step 3: Tap “Other security settings”.

Step 4: Tap “SIM card lock”.

Step 5: Tap “Lock SIM card” and you will be asked via a pop-up to enter the PIN. Now, as I have told above, the default PIN will be either 1111 or 1234. If not, you can easily Google or call your carrier for this. No big deal.

Once the Sim card lock is activated, you can tap on “Change SIM card PIN” to change as per your will.

Step 6: To disable the SIM card lock, tap “Lock SIM card” again and enter your PIN.

Summary:

Settings> Lock Screen and Security> Other security settings> SIM card lock> Lock SIM card> Change PIN> Restart Device

Warning

Remember this very clearly that if you entered the SIM PIN incorrectly three times, your SIM will be deactivated and you will need to contact your carrier for a new SIM card. Set a PIN that is easier for you to remember to avoid this inconvenience, yet not too easy to be guessed by a criminal. Be artistic but in a unique way.

The Bottom Line

It always has been a point of worry when it comes to securing your phone and cybersecurity. There are certain times people slack off the need to worry about these things and end up being compromised by hackers.

Don’t worry, you can always add this SIM Card Lock as an extra layer of security on your android device and your SIM card will be safe from hackers making unsolicited connections using your name or even leaking your information.

How to set up sim card lock for a more secure android phone

There are a few things you can do to make sure your Android phone stays as safe as possible should it stray from your hands—a good lock screen password is a solid start. What you may not realize is that there’s a way to take that security a step further by enabling SIM Lock.

Before we discuss how to enable SIM Lock, let’s first talk about what it isn’t. Judging by the name, it’s easy to assume that this is some sort of setting that will sound an alarm should the installed SIM be removed. That’s not what this is, however. Essentially, SIM lock requires your lock screen PIN, pattern, password, or fingerprint and SIM card to be in place before the phone can be unlocked. You can kind of think of it as physical two-factor authentication, which deters thieves from removing the SIM in order to avoid being tracked.

Now, a few things you should be aware of before setting up SIM Lock. First off, you’ll need to know your carrier’s default unlock code. For many, this is just 1111, but be aware: if you enter this incorrectly three times, it will render your SIM useless (that’s part of the security of it, after all). You can start by trying 1111, but if that doesn’t work on the first try, you’ll probably need to contact your carrier to get the default code.

Secondly, and this should really go without saying, but if your carrier doesn’t use SIM card, then SIM Lock won’t work (and probably isn’t even available on your handset). So this article isn’t for you.

With that out of the way, let’s get into it.

The first thing you’ll need to do is jump into the Settings menu. On most phones, you can do this by pulling down the notification shade and tapping the cog icon.

How to set up sim card lock for a more secure android phone

Once in the Settings menu, things can get even trickier—every manufacturer does their own thing in this menu, so there’s no clear way to say “tap this, then this, then this.” So the easiest thing to do will be to use the Search tool, which is generally found in the top right corner. Tap that, then type “SIM Lock.”

If it’s available on your phone, then “Set up SIM card lock” will show up at the top of the list. If not, well…I’m sorry.

Go ahead and tap that option, which will open the SIM Lock menu, which is super simple—it’s literally two options. When you tap the “Lock SIM card” box, it’ll automatically prompt for the SIM PIN and show how many attempts you have left. Like stated earlier, the default is usually 1111, but if that doesn’t work, you’ll need to contact your carrier to find out what they use.

Once you’ve entered the correct PIN, SIM Lock will be switched on. At this point, you’ll want to tap the second entry in this menu: Change SIM PIN. You’ll enter the current PIN (again, the default), then select one of your own between four and eight digits. Make it hard to guess, but easy to remember (it can be different from your normal lock screen PIN). If you forget, you’ll only have three tries to get it right before your SIM is toast!

After you confirm the new PIN, you’re all good. From now on, the phone will require both your current lock screen security entry and the locked SIM to be installed before it’s usable. Solid.

This is probably one of the least-used security methods available in Android, despite being around for many years at this point. It’s an excellent tool to add an additional layer of protection against would-be wrong-doers should your device get lost or stolen.

How to set up sim card lock for a more secure android phone

Decided to forbid access to your smartphone? There are many ways to do that, although some also only protect your smartphone or encrypt your data. If that’s the case, you don’t shield your phone number or personal/billing information from abuse. The easiest way that includes the SIM card is the built-in protection in form of a PIN (Personal Identification Number) code. If that term sounds familiar, recall the time we mentioned PIN as part of the ways a SIM card can be unlocked. But, we never got into the process of enabling that security in the first place. We’ll fix that now by teaching you how to lock a SIM card.

Words of warning

Some carriers put default PIN code, but the SIM card lock is disabled in smartphone software. Even if the SIM card is locked, it isn’t secure. That’s because carriers always use the same PIN combination, such as 0000 or 1111. If that’s your case, you only have 3 attempts to enter the correct PIN before the SIM card asks you to find a PUK code. After following the steps below, use 1st and 2nd attempts for the combinations we mentioned. Reserve the 3rd attempt for contacting your carrier and getting a clear answer.

Guide to lock a SIM card on Android

  4. The Lock SIM card option will be disabled. Toggle the switch icon to on.
    On some smartphones, you need to select an option named PIN or Encryption and credentials beforehand.
  5. If it says Enter current PIN, we explained what to do next.
  6. If it asks you to set a PIN, pick a 4-digit number. Make all 4 numbers different, but not in ascending or descending order such as 1234 or 9876.

For Apple tablets using iPadOS (based on iOS), the process is almost identical. The key difference? The developers named the Cellular option Mobile Data.

Is locking a SIM card remotely possible?

A SIM card can be locked remotely, but not by you. Carriers or phone manufacturers do this to apply technical restrictions. Those restrictions can be irreversible such as blocking a SIM card. On the other hand, blocking access to the SIM card can also be temporary or permanent, but reversible. An example of this is putting a lock and key on a SIM card based on region, network, or phone manufacturer. The last option is common with SIM cards that ship with some Nokia smartphones.

Much like a lock screen PIN code, a SIM PIN code is a way to make sure nobody can use your SIM card without knowing the correct code. Whenever a SIM card with a PIN set is first placed in a phone, you’ll need to know the PIN to unlock it for use. It’s easy to set a SIM card PIN, but you do need to make sure you’re prepared ahead of time.

Products used in this guide

  • Still a great phone: OnePlus 8 ($610 at Amazon)

What is a SIM PIN?

Very simply, a SIM PIN is a code, usually between four and six digits, that prevents a SIM card from being used if placed in a new phone, or even after rebooting a phone it’s currently inserted into. This is meant to ensure that a stolen phone cannot be used to make phone calls, or to prevent unauthorized access to a protected or secure phone number.

SIM PIN codes are not that common anymore, but they’re often implemented in prepaid SIM cards that you purchase from a store or MVNO.

Getting ready

  1. If you are setting a SIM card PIN code for the very first time you’ll need to be able to talk to the carrier who issued the SIM card. You’ll need to get what’s called a PUK code which the carrier provides as well as instructions about entering it; some carriers have you enter a PUK code through the phone dialer and some have you enter it during the SIM card PIN code setup.
  2. It’s best to have access to another working phone in case you’re locked out and need to talk with the carrier that issued your SIM card.

Use your phone’s settings

    Open the settings on your phone and look for the entry marked Security & privacy.

  • Choose the entry marked SIM card lock and tap on it.
  • In the next screen enter slide the toggle to enable locking your SIM card.
  • Enter your SIM card PIN code in the window that opens and save your settings.
  • Source: Jerry Hildenbrand / Android Central

    If you enter an invalid PIN code more than three times you’ll be locked out of service and need to talk with the carrier that issued the SIM card. Remember, if you’re doing this for the first time you’ll also need to talk to your carrier.

    Do you really want or need a SIM card PIN lock? This doesn’t affect the security of your phone in any way and is a holdover from a time when SIM card theft was more prevalent and the number of calls, texts, and data was much more limited by your carrier.

    If you have a real need for making sure nobody can remove your SIM card and use it elsewhere, this is the cure. Just be ready to make a call to customer support before you get started or in case there is a problem.

    Fast and simple

    OnePlus 8

    The Interstellar Glow is to die for.

    While not the latest from OnePlus, you get a great screen, 5G from T-Mobile and AT&T, and a mid-range price. Top that all off with plenty of storage and a good camera and the OnePlus 8 is still a winner.

    Disclaimer: Almost every Android phone and every carrier supports using a SIM card PIN lock, though there may be minor d differences in exactly how it’s done. This guide uses the OnePlus 8 but you should be able to navigate your way to using a SIM PIN using this guide with any phone.

    If your SIM card has a PIN lock, you will be required to enter your secret PIN code every time the SIM card is first used, such as when turning the device’s power on, or when turning off Airplane mode. The PIN lock is recorded to the SIM card itself, meaning that it helps protect the SIM card from unauthorized use when inserting it into other devices.

    Given that smartphones and other devices with SIM cards are usually left in a constantly-connected state (including in standby mode on an Android device), situations requiring the PIN unlock code are relatively rare. PIN unlock codes only protect the SIM card and do not protect against using the device for features that do not depend on the SIM card, such as for communication over Wi-Fi networks, or using the device if an alternative SIM card is inserted.

Obtaining your PUK code almost always means contacting your carrier (the company that provided the SIM card to you) and asking them for the PUK code. They may provide a way of finding this out in their online account tools.

    Change SIM PIN

    Allows changing the secret PIN code for your SIM card.

    To change this setting, you will be required to enter the existing SIM PIN. If you do not know the PIN code for your SIM, it is often set to 0000 (four zeroes) if you have never used PIN locking before on it.

    What Is TLS Certificate? A Comprehensive Overview (2021)

    INTRODUCTION With the recent cyber crime cases, it becomes imperative for ensuring the best means to transfer data for avoiding any sort of tampering or leakage of information. It is necessary for privacy and performance improvisation. TLS is the most reliable security protocol and has been widely accepted by many businesses for the secured transmission of data. TLS web connection requires a TLS certificate. What is TLS?What is a TLS Certificate?How does a TLS certificate work?Weaknesses of a TLS CertificateTrusting Certificate AuthoritiesSpecial Precautions by ProtonMail 1.What is TLS? TLS stands for Transport Layer Security. It is adopted as a security protocol for transmitting data online to facilitate end-to-end communications and online transactions. It ensures encrypting of data for communicating between web-based applications and servers. It can also be used for encrypting instant messaging, VOIP, e-mails. TLS protocol helps prevent forgery, hacking, eavesdropping, tampering of the messages, passwords, credit card credentials, data, personal correspondence being communicated across networks. In the case of TLS vs SSL, TLS was proposed by Internet Engineering Task Force (IETF) in the year 1999 and SSL by Netscape. Many organizations are using TLS to ensure the secure transmission of sensitive data as they can multiplexing and demultiplexing services with guaranteed bandwidth. 2.What is a TLS Certificate? A TLS certificate is a kind of digital certificate (or public key certificate/ identity certificate) issued by the Certificate Authority. The certifying authority authenticates the certificate by signing it, certifying that it belongs to a particular domain name which is the subject of the certificate. The details of the certificate include the subject domain name, organization, owner of the certificate, the public key of the server, which is essential for validation of the identity of the server, the certificate-issuing authority, issue and expiry date and many such details. 3.How does a TLS certificate work? A TLS certificate consists of a public key and a private key that interacts behind the scenes during the transactions. They ensure secure encryption when someone visits a website. After receiving the directions for moving to a secured website, the TLS certificate and public key get shared with the client for secure connectivity and a unique session key. The browser then confirms the authenticity of the certifying authority and the status of the certificate. The browser sends the symmetric key, and the server decrypts using his private key. This is then acknowledged by the server encrypted with a session key for starting the encrypted session. Thus this transmission of data with the session key helps in the privacy and integrity of the message. TLS handshakes initiate when a user navigates to an application or website that uses TLS and is a multi-step process. This aids in authenticating the identity of the server, generation of sessions for TLS encryption of messages and establishes a cipher suite for the communication session. The protocols using handshakes with an asymmetric cipher establish better communication using a symmetric cipher. With this, details of encryption or session keys will be used with the help of public-key cryptography. After the authentication and encryption of data and signature with the message authentication code, the recipient can authenticate for ensuring the integrity of the data. If any steps fail, then the handshake would fail to result in the connection not being created. 4.Weaknesses of a TLS Certificate: The greatest loophole existing in the digital era is of the hackers, intruders and cyber scams. TLS Certificate is also affected by them. A few of them are mentioned as under: Poisoning the TLS certificate If the computer gets attacked by malicious software, then the security of the TLS certificate is threatened. This would lead to the insertion of a root certificate which can cause responding to the user’s request fraudulently, impersonation of a website and gaining access to all the data. Direct attacks on the Certifying Authority A direct attack on the certifying authority could lead to unauthorized usage of the authorization keys. Certificates issued by error Users allow the certifying authority to authenticate the server for connection purposes. However, the vulnerability arises when the hackers exploit the certificate. This could lead to misuse of the certificate and compromising the connection issue on the server. 5.Trusting Certificate Authorities: The setup of a CA consists of a Public Key Infrastructure that consists of many components like security infrastructure, auditing systems, practice statements, policy frameworks, all of which are essential for making the certificate secure and reliable. The model of PKI runs on two systems- root certificates and server certificates. If the root certificate is installed on your device’s certificate, it will be easily trusted by the browser. Similarly, every device has a local collection of root certificates from trusted CAs. 6.Special Precautions by ProtonMail: Enhancing security and privacy has been the main aim of ProtonMail. Few additional measures are as follows: DNS Certificate Authority Authorization (CAA) When the instances of wrongly issued certificates came in, the need for DNS CAA was felt for blocking the issuing of wrong certificates. This aids in protection against misuse of the unintended certificate. Certificate Transparency The CAs post the certificates on the public log servers for validity and to prevent misusage. TLS Certificate Pinning This is a process for linking services to their specific public key. For validation, at least one element from the service matches with the elements in the pinset. CONCLUSION With the TLS security enhancement, the certificate is constantly updated with better versions, performance, TLS connection, and functionality. Several attempts have been made for revising the issues for addressing security concerns for defending the position against potential weaknesses. This aids in several benefits like ease of use, deployment, the flexibility of algorithm, interoperability and many more. So, have you made up your mind to make a career in Cyber Security?

    Enhance your SIM-security by setting up a SIM PIN lock: Smartphone users usually protect the data stored on their devices by setting up a biometric lock, PIN, or passcode. But what about the data stored in SIM memory? What if someone takes out the SIM card and starts using it on another phone? Remember, it contains a lot more information other than just phone numbers. This includes billing information and transaction OTPs too come through SIM card.

    Enhance your SIM-security by setting up SIM PIN lock Simply put, a smartphone’s lock screen does not lock the SIM card inside it, or even setting up an app lock or encrypting the entire smartphone or using the boot-time password on your smartphone does not protect the SIM card or its data.

    Well, then how to protect the SIM card and the data stored on it. The answer is SIM PIN, which is also the only way that adds an additional layer of protection to the SIM. Once the SIM PIN lock is enabled, each time you’ll restart the smartphone or swap the SIM to some other smartphone, it will ask you to enter your SIM PIN and without the authentication, SIM card will not be accessible at all.

    Do note that in case you forget your SIM PIN and you will need to call customer care. As it will ask for PUK (PIN Unlock Key) code to unlock the SIM.

    Enhance your SIM-security by setting up SIM PIN lock?

    Step 1: Go to Settings and tap on Security

    Step 2: Now, tap on Other security settings or More security settings

    Step 3: Tap on Set up SIM card lock

    Step 4: Enter default PIN of your SIM card

    The default SIM PIN differs from operator to operator. For example, Airtel users can enter 1234 and the default SIM PIN for Vodafone users is 0000.

    Step 5: To change the default SIM PIN, tap on Change SIM card PIN.

    Step 6: Enter the current PIN to verify and then enter the new PIN of your choice and confirm it again to save the new PIN.

    How to set up sim card lock for a more secure android phone

    Hay algunas cosas que puede hacer para asegurarse de que su teléfono Android permanezca lo más seguro posible en caso de que se le escape de las manos: una buena contraseña de pantalla de bloqueo es un buen comienzo . De lo que quizás no se dé cuenta es de que hay una manera de llevar esa seguridad un paso más allá habilitando el bloqueo de SIM.

    Antes de discutir cómo habilitar el bloqueo de SIM, primero hablemos de qué . A juzgar por el nombre, es fácil suponer que se trata de algún tipo de configuración que hará sonar una alarma si se retira la SIM instalada. Sin embargo, eso no es lo que es. Básicamente, el bloqueo de SIM requiere el PIN, el patrón, la contraseña o la huella digital de la pantalla de bloqueo La tarjeta SIM debe estar en su lugar antes de que se pueda desbloquear el teléfono. Puede pensar en ello como una autenticación física de dos factores, que disuade a los ladrones de quitar la SIM para evitar ser rastreados.

    Ahora, algunas cosas que debe tener en cuenta antes de configurar el bloqueo de SIM. En primer lugar, deberá conocer el código de desbloqueo predeterminado de su operador. Para muchos, esto es solo 1111, pero tenga en cuenta: si ingresa esto incorrectamente tres veces, inutilizará su SIM (eso es parte de la seguridad, después de todo) Puede comenzar probando 1111, pero si no funciona en el primer intento, probablemente deba comunicarse con su proveedor para obtener el código predeterminado.

    En segundo lugar, y esto debería ser evidente, pero si su operador no usa la tarjeta SIM, entonces el bloqueo de SIM no funcionará (y probablemente ni siquiera esté disponible en su teléfono). Entonces este artículo no es para ti.

    Con eso fuera del camino, empecemos.

    Lo primero que debe hacer es acceder al menú Configuración. En la mayoría de los teléfonos, puede hacer esto bajando el tono de notificación y tocando el ícono de engranaje.

    How to set up sim card lock for a more secure android phone

    Una vez en el menú Configuración, las cosas pueden complicarse aún más: cada fabricante hace lo suyo en este menú, por lo que no hay una forma clara de decir “toca esto, luego esto, luego esto”. Entonces, lo más fácil de hacer será usar la herramienta de búsqueda, que generalmente se encuentra en la esquina superior derecha. Toca eso y escribe “Bloqueo de SIM”.

    How to set up sim card lock for a more secure android phone How to set up sim card lock for a more secure android phone

    Si está disponible en su teléfono, “Configurar bloqueo de tarjeta SIM” aparecerá en la parte superior de la lista. Si no es así, bueno . lo siento.

    Continúe y toque esa opción, que abrirá el menú de bloqueo de SIM, que es súper simple, son literalmente dos opciones. Cuando tocas la casilla “Bloquear tarjeta SIM”, automáticamente te pedirá el PIN de la SIM y mostrará cuántos intentos te quedan. Como se indicó anteriormente, el valor predeterminado suele ser 1111, pero si eso no funciona, deberá comunicarse con su proveedor para averiguar qué utilizan.

    How to set up sim card lock for a more secure android phone How to set up sim card lock for a more secure android phone

    Una vez que haya ingresado el PIN correcto, el bloqueo de SIM se activará. En este punto, querrá tocar la segunda entrada en este menú: Cambiar PIN de SIM. Ingresarás el PIN actual (nuevamente, el predeterminado), luego seleccionarás uno de entre cuatro y ocho dígitos. Haga que sea difícil de adivinar, pero fácil de recordar (puede ser diferente de su PIN de pantalla de bloqueo normal). Si lo olvidas, ¡solo tendrás tres intentos para hacerlo bien antes de que tu SIM se desmorone!

    Después de confirmar el nuevo PIN, todo estará bien. A partir de ahora, el teléfono requerirá que se instalen tanto la entrada de seguridad de la pantalla de bloqueo actual como la tarjeta SIM bloqueada antes de poder utilizarla. Sólido.

    How to set up sim card lock for a more secure android phone

    Este es probablemente uno de los métodos de seguridad menos utilizados disponibles en Android, a pesar de haber existido durante muchos años en este momento. Es una herramienta excelente para agregar una capa adicional de protección contra posibles malhechores en caso de pérdida o robo de su dispositivo.

    On my Samsung Galaxy SIII, one can go to Settings -> More -> Security -> SIM card lock -> Set up SIM card lock -> Change SIM PIN to change the default PIN that came with the SIM card. But what about the PUK (the 8-digit number that comes with the SIM card to unlock the card after 3 failed 4-digit PIN number attempts)? Can the PUK also be changed from within the Android GUI, or is it a fixed number stored on the SIM card which cannot be changed?

    3 Answers 3

    The PUC (PUK) is a SIM-specific code assigned by the service provider. – Personal Unblocking Code (Wikipedia)

    That means you cannot change it with help of your android device.

    If you want to crack it you must watch this video

    Video is about ‘Rooting The Sim’ by Karsten Nohl at BlackHat 2013.

    In this video Nohl showed vulnerability that almost every sim have which was manufactured before 2013(Also Some cards after that whoes providers have not fixed this security hole)

    Procedure -Send binary sms with OTA command to card requesting response

    -Crack DES signing key that sign Java virus and sent through binary sms

    -Leverage gaps in Java VM memory separation to access arbitrary sim card data

    Results -Card may response with DES signed error message

    -Card install and execute signed Java applet

    -Malicious applet extract ki,banking applet etc. and send ti attacker via sms

    Once an attacker cracks the key, he can commit premium SMS fraud, circumvent caller-ID checks, manipulate voice-mails, redirect incoming calls and text messages, abuse USSD payments, track and phish users, install malware on their devices, or perform any other browser-based attack. With data access enabled, Nohl claims an attacker can clone SIM cards, decrypt 2G, 3G, and 4G traffic, clone NFC takers and future SIM applications, and alter the operating system to prevent future patching.

    Nohl also claims to have been able to break out of the SIMs Java sandbox and get access to this personal unblocking key

    Now you have that set up, let’s take a look at tips for keeping your phone and the information it stores out of the wrong hands. Remember to update your passcode every 2-3 months to keep it extra secure.

    Three tips for creating a strong passcode for your smartphone

    1. Think of numbers as letters to help you create a passcode that is challenging, but something that will be memorable for you. For example, if you’re a foodie with a sweet tooth, you might use CAKE (2253) or PIES (7437).
    2. Avoid obvious number combinations like 1-2-3-4 or repetitive codes like 1-1-1-1.
    3. Don’t use numbers that can be easily guessed like your birth date, anniversary, your phone number, etc.

    Two factor authentication: should I set it up?

    If you use iCloud or Google accounts you’ve probably heard of two factor authentication. It’s a security method that asks you to take an extra step — usually entering a code — to confirm your identity when you log into email, social media, or other password protected accounts. This second layer of protection is designed to keep other people from signing in to your account, even if they have your password. Check out our guide on how to set up two factor authentication for more information.

    How to set up sim card lock for a more secure android phone

    The SIM PIN code is a security feature that protects against unauthorized individuals accessing your SIM card data. Some smartphone models come with this option on by default, while others need to have the feature enabled.

    A vast majority of carriers provide standard SIM PIN codes like 0000 or 1234, while others generate random codes. In any case, it’s always a good idea to change the default code in order to boost the security of your device and prevent someone from simply guessing what your code is.

    In this article we examine how you can easily change your SIM PIN on your device. In addition, it’s possible to remove the code altogether if you are confident that your device doesn’t need the extra layer of protection.

    Why It’s Important to Lock Your SIM

    Your SIM card doesn’t just contain your address book. Actually, the small plastic card also stores other valuable data, including SMS text messages, billing information and data usage.

    As it happens, this data can’t be secured merely by setting up a PIN, passcode or some type of biometric lock on your phone. Only by activating the SIM PIN lock can users make sure this information will be secured against any potential hacking attacks.

    How to Turn on SIM Lock

    In order to turn on the SIM lock feature on a device that doesn’t have it activated by default, you will need to know your phone’s default SIM PIN. As we mentioned above, most carriers use defaulta, but that’s not always a rule. In the U.S., two of the biggest carriers – Verizon and AT&T – use 1111, while T-Mobile and Sprint employ 1234 instead. Typing in

    If these codes don’t work for you, then you should try to call your carrier or check your provider’s website in order to obtain the default SIM PIN. Make sure you have the correct information before typing the code, though, because if the number of PIN input attempts exceeds three times, your SIM will get blocked. In order to unblock it, you will need to enter the PUK to unlock the SIM. The PUK is the PIN Unlocking Key that is usually delivered with your SIM card.

    Once you’ve obtained your default SIM PIN, the next step is to turn on the SIM lock feature manually on your device. The path will vary based on your smartphone model and the Android version it’s using. For the purpose of this tutorial, we used a OnePlus running Android 10.

    1. Open the Settings app on your phone.

    2. Scroll down until you find “Security & Lockscreen.”

    Every time you fire up the device or reboot it now, you will be required to input the default SIM PIN number.

    Alternatively, on other devices you may need to follow a slightly different path like “Security & Privacy -> More Settings -> Encryption and credentials” to find the SIM card lock.

    On an older Honor device running Android 8.1 Oreo, the feature is located under “Settings -> Security & Location -> SIM card lock.”

    Bottom line, make sure you look for the option in the Security/Privacy sections of your phone’s Settings. If you can’t find it on your own, try and perform a search in Settings using the keywords “SIM” or “Lock.”

    How to Change Your SIM PIN Code on Your Android?

    On the other hand, if you want to simply change your default code to something else, these are the steps to follow in order to do so.

    1. Open the Settings app.

    How to set up sim card lock for a more secure android phone

    Almost all of us have heard about ‘phone lock’ and even ‘app lock’. These are nothing but a layer of security with an aim to protect sensitive data from someone who tries to get access without consent. But many might not have heard about ‘SIM lock’. To clear it out, this is not a new tech and no, it doesn’t alarm the handset owner or authorities if you try to remove it. It’s dug inside your handset’s Settings app and is in fact a really useful feature.

    What it does? SIM Lock essentially locks the SIM to the handset it is placed in. This means that when you remove the SIM card and place it in a different handset, it will ask for the PIN code that was set for the SIM. Similarly, when you insert a new SIM card in the handset that was already set with a SIM lock, it will again ask for the PIN code to operate.

    This is useful mostly when the smartphone is stolen and when the thief tries to replace the SIM card with a different one. So today we tell you a few steps on how to activate it on Samsung phones, iPhones, Realme and Poco phones you know, just in case.

    SIM lock on Samsung phones (OneUI 2.0):

    -Open Settings app.

    -Tap on the ‘Biometrics and security’ option.

    -Scroll down and tap on the ‘Other security settings’.

    -Tap on Set up SIM card lock by inserting the PIN.

    SIM lock on Realme phones (RealmeUI on Android 10):

    -In ‘Settings’ app, open the ‘Security’ option.

    -Tap on ‘SIM card lock’ and set it up.

    SIM lock on Apple iPhones:

    -In ‘Settings’ app, open Cellular.

    -Tap on SIM PIN and set it up.

    Similar step for iPad with cellular connectivity.

    SIM lock on Poco phone:

    -In ‘Settings’ app, open ‘System & device’

    -Select ‘Privacy’ and set up SIM lock.

    How to set up sim card lock for a more secure android phone

    From the humble passcode to biometric authentication, there are quite a few options to lock your Android phone. But which of them are more secure than the others?

    As people become more sensitive about the privacy and security of their data, you’d think that securing your phone with at least some kind of authentication measure wouldn’t even be up for discussion. That would be far from the truth, however. According to a report by the Pew Research Center, almost a third of Americans don’t use any kind of screen lock. We gave this some thought recently when discussing how in 2020 to improve the security of your phone.

    This time, we’ll dig a little deeper and look into the different authentication methods your Android devices offer.

    Pattern lock

    A pattern lock, as the name suggests, requires a specific owner-defined pattern to unlock the device. As far as screen lock choices go, pattern locks could be considered a medium-level security option at best. Your finger squiggle could be as easy as drawing an L or you could make the pattern more difficult by drawing a sophisticated shape. The simpler the pattern is, the easier it is for lurkers to copy it if they are watching over your shoulder.

    In fact, research found that lurkers were successful in recreating the swipe pattern 64.2% of the time after looking at it once; with multiple observations, that risk rises. You can improve your security by turning off feedback lines and opting for a more sophisticated pattern. All things considered, however, a PIN or a password is generally a safer option.

    PIN/password

    If you’ve been smart and set up any protection at all on your Android devices, you’re probably familiar with the PIN lock/password option, because it is the code your SIM card asks you to enter whenever you turn off and turn on your phone again. Many Android versions will allow you to set a paltry four-digit code, but if you care about your security, you will choose a much longer PIN code.

    If you want to up your lock game, you should probably opt for a password that incorporates letters, numbers and special characters and make it at least 8 characters long. It may be a bit harder to remember and type out, but in the long run you’ll be glad you played it safe. If you really want to up the ante, you can also turn on the feature to wipe your phone after a number of failed login attempts.

    Fingerprint

    Fortunately for some of us, fingerprint biometric locks are still a thing. You may encounter different varieties, with some being standalone locks, others incorporated into buttons and the latest development are the ones hidden in the smartphone screen. The case for these is that the fingerprint lock can be considered to be one of the fastest ways to secure your phone. By placing your finger on the reader your phone will unlock within a fraction of a second.

    But is it foolproof? Well, where regular people are concerned it’s highly doubtful that a bad actor would go through the ordeal of trying to get through a biometric lock. Still, bypassing a fingerprint lock isn’t entirely impossible. Fingerprints can be stolen from photos and other sources, then recreated, even with just 2D printing, and then used to bypass biometric locks. In 2017, one security researcher was able to recreate the fingerprint of Germany’s Minister of Defense from high-resolution photographs.

    Face scan

    This biometric lock does exactly what it says: it scans your face. Although you’d imagine that the process is fairly sophisticated and entails a large number of technological wonders, the truth is it basically relies on your front camera and some software. The camera scans an image of your face and then relies on a facial recognition algorithm to verify your face. The speed of the unlock also depends on your phone and the quality of its front-facing camera.

    The measure isn’t necessarily that secure and a bad actor may fool it with a photo of your face. Actually, researchers conducted a test on 110 different smartphones and what they found didn’t paint a pretty picture. In general, having a fingerprint biometric lock in combination with a passcode is the more secure way to go.

    Brand-specific features

    Different brands of smartphones are also putting their takes on biometric security measures by adding special features to bolster the security of their devices. Those range from various levels of face scanning to iris scans. Samsung, for one, has its own version of the iris scan, which is quite simple to set up. It also considers whether you wear glasses or not. The technology uses an infrared LED to illuminate your eyes while a narrow focus camera captures the iris patterns and the smartphone processes that information. Sounds very high-tech, doesn’t it? But is it secure? Well, a team of white hat hackers using a camera with an infrared feature was able to trick the first of Samsung’s phones to offer the feature.

    Final verdict

    There’s quite a variety of lock options to choose from. It’s always wise to choose a combination of features and not to rely solely on just one. But arguably the safest option on the list is the trusty PIN or password of sufficient length and complexity, with a fingerprint scan coming in next. Whichever option you choose, it’s always smart to plan ahead. Securing your phone now might save you from a nasty headache in the future.

    How to set up sim card lock for a more secure android phone

    What’s the number one thing you can do to secure your phone and any data ? The answer is simple, but many smartphone owners still don’t consider this basic yet essential feature – even when it minimizes the risk of data or identity theft, loss of privacy, theft, etc. Can you guess what the answer is?

    Easy – lock your screen

    Before you take the time to install the latest antivirus software on your device, encrypt your data / messages and attempt a range of other complex security measures, the most important thing you should do is always set up a locking method on your lock screen. Yes, the answer really is that simple – I mean, would we lie to you about that?

    You’d be surprised, however, about how many smartphone owners don’t protect their lock screen with either a PIN, pattern, fingerprint or another method, meaning the home screen can be activated by a simple swipe. Sure, you save time, especially if you are a constant phone-checker, but I cannot stress the importance of this enough.

    What are the risks if you don’t lock your screen

    The first risk is visual hacking: if you are checking your phone in public, prying eyes could be looking over your shoulder, so it’s best to check sensitive information privately and not in a packed bus. If your phone is left somewhere unattended, someone could easily read your messages, access your banking app or other personal data. Having a lock screen would nullify this risk.

    Having your phone stolen: if you lose your phone or if it is stolen, not having a lock screen or a pin for your SIM is bad news. Perpetrators use SIM readers or scanners in order to grab information from your SIM card, then use it to make phone calls. Chances are they don’t call locally, resulting in massive bills you have to pay for. Thankfully, carriers often act fast in these situations and help resolve the problem. But it is better not to risk this in the first place.

    Digital identity theft: if someone gets a hold of your phone, they could do more than just place calls. They may use your social media accounts to post damaging information or worse, access credit card and social security numbers, if these happen to be in emails or saved in apps. People who fall victim to identity theft often are plagued by the issue for years, seeing as the information is continuously sold and used for other illegal activities.

    How do you lock your screen?

    Scared yet? Don’t be. Just set up a lock screen on your Android phone or tablet, it’s a simple thing to do that could save you a lot of grief. Every manufacturer has a slightly different setup, and some newer phones, such as the Galaxy S7, feature a fingerprint reader for extra security.

    To access the lock screen settings on an Android phone, a common path would be go to your Settings, then Security and the first option is Screen lock. You can then set up a pattern, PIN or password. The pattern can also be made invisible, as opposed to showing the grid of dots. Furthermore, you can decide how quickly your phone automatically locks. Some other good available features are the ability to encrypt your phone, set up a SIM card lock and Android Device Manager, the latter allowing you to lock or erase a lost or stolen device remotely via a web browser.

    Hardware encryption: how does it help?

    When you set up your screen lock, such as entering a password, a PIN or a pattern for unlocking, the setup assistant asks you a very important question: Do you want to activate “Secure start-up”? This provides an additional level of protection for your phone’s internal memory.

    Admittedly, the system does have a few downsides. If at anytime you need to restart your smartphone, you must enter the code early on in the start process as if you don’t it will block the home screen and essentials like the alarm clock won’t start. Even if you go to bed with your smartphone is switched on and your alarm set you won’t be woken up.

    Nevertheless, it is an important protection as any thieves who manage to steal your phone will have a harder time resetting the device. Because the standard degree of Android encryption receives an additional level of encryption, this ensures that both your data and overall device are better protected. Even professional methods to reset the device or change the firmware become considerably more complicated.

    Do you use a lock screen? What are other things you can do to protect your phone and its contents? Let us know in the comments below.

    What to do if you are unable to turn off PIN, password or pattern unlock on Android

    How to set up sim card lock for a more secure android phone

    This is a post from our smartphone FAQ section. To see other questions please click here. To see browse the Android phones that we sell, see our smartphones section on the Clove website. In order to use certain features on your Android device, you will be required to set a PIN, pattern or password lock; these are the three most secure methods for locking the device. When one of these is required, the two other methods, slide or face unlock, will be greyed out and display the message ‘Disabled by administrator, encryption policy or credential storage’. If you are unable to disable PIN, password or pattern unlock on your Android device, it is likely that you have the setting in place in order to use one of the following functions (see a more detailed description for each one after the list below):

    • Screen security. This is located under settings > security > screen security
    • Device Encryption. This is found under settings > security > encryption.
    • Setting a device administrator. This is found under settings > security > device administration
    • VPN. This is found under settings > more > VPN

    The first three in the list above are fairly easy to spot as they are all located under the security section of the settings menu. However, it can be easy to forget that you have set a password in order to use a VPN, so if having checked it is not one of he first three requiring a PIN, be sure to check that you have removed any VPNs.

    Changing Screen Security

    Screen security is either set by you, or can be required by a device administrator (app). If it is the case that you have set a PIN, password or pattern, you can easily turn it off or choose another locking method by going to settings > security > screen security. If you are unable to remove the security setting and see the message ‘Disabled by administrator, encryption policy or credential storage’, it is likely because of one of the settings described below.

    Device Encryption

    Device encryption is activated or deactivated from settings > security > encryption. If you encrypt the device, a PIN/password/pattern is required each time you turn the device on. It makes your data more secure should you lose the device and takes around an hour to set up. If you are unable to remove the PIN code from your phone, check that you have not encrypted the handset. You can do this by looking under the encryption part of the settings menu.

    Removing a device administrator

    Some applications will require administrator access to your device in order to perform certain actions. When using an app that requires administrator access, it will usually prompt you from within the app to turn on administrator access. The majority of apps that do this will also show a message to inform you that you need to revoke administrator access before uninstalling the app, which is important.

    Some apps only require administrator access to perform certain actions, so you do not necessarily need to grant administrator access to use the entire app, but only to use certain features. Sometimes the app will require that you set a secure lock method as part of its administrator access. One such example of this is adding an Exchange email account. You need to grant the app administrator access with certain permissions and set a secure lock method. This is usually so that the device can be accessed remotely if lost or stolen.

    If you are unable to remove the PIN setting from your device, it may be because an administrator is requiring it. You can revoke administrator access by going to settings > security > device administration and then unticking the box next to the apps on the list. If it is an account, such as email, that is requiring the security setting, you will also need to remove this from your device in order to remove the PIN lock.

    Adding or removing a VPN on Android

    When setting up a Virtual Private Network (VPN) on your device, Android now requires that you have a secure lock method in place. Seeing as this is the case, it would make sense to have the VPN menu under security settings, but it isn’t at the moment. This makes it easy to forget that you have set up PIN security for it. If you have tried changing the three settings described above but your handset still requires a PIN number, you may have a VPN that needs removing. To do this navigate to settings > more > VPN, long press on any networks that have been added and then select remove.

    Stop worrying and check out these simple steps to secure your mobile

    How to set up sim card lock for a more secure android phone

    Like every geek, I have been asked to set up security basics on computers for family and friends. But these days, I get asked more about mobiles and websites than computer by friends who want to be safe online and minimize loss when they misplace their phones or other devices. Over a couple of years, I have made a check-list that I share with them, which may be of use to you too.

    These are simple steps that you can follow to keep yourself safe from everyday attacks on mobile and web. If your threats are bigger, talk to someone who is an expert in security. With that disclaimer, let’s look at some of the common tools and practices that we all can follow.

    PINs for both your phone and SIM

    Most of us are familiar with phone passcodes, but sometimes they are too short and can easily be guessed. Just make sure your PIN is at least six digits long.

    Setting up a SIM PIN is just as important. Most online services, including some banking services, confirm accounts using SMS or USSD. If you ever lose your phone, some one can take over your accounts by using the SIM. SIM PIN restricts someone from accessing your SMS OTPs and USSD (Unstructured Supplementary Service Data) by plugging the SIM into another phone. Prevent that with a SIM PIN.

    If you go to your Phone – Settings – Security – SIM card lock, you can change the SIM PIN. The default PIN for the SIMs would depend on the provider. The most common ones are below. If they don’t work then try calling customer service.

    Provider SIM PIN
    Airtel 1234
    Vodafone 0000
    BSNL 0000
    AirCel 0000
    Idea 1234
    Tata Docomo 1234

    Please note that you will have to enter the SIM PIN each time you restart the phone or the SIM gets activated. If you enter the wrong PIN thrice, the SIM gets locked and you will get an alert asking for the PUK (Personal Unlocking Key) code. The PUK code is provided by the mobile service provider. You can call them and get the PUK code to unlock your SIM.

    Full disk encryption

    Most modern smart phones (iOS and Android) have the option for full disk encryption. Enable it. On Android go to Settings – Security – Encrypt Device

    Public Wi-Fi and VPN

    My advice is not to use public Wi-Fi as much as possible. But there will be situations when you have to use public Wi-fi. Then it’s important to use a VPN (Virtual Private Network) to secure your communications. There are hundreds of providers to choose from. Do a thorough review before getting a subscription (I use PrivateInternetAccess).

    Apps, software maintenance

    Stay up to date with the firmware. Check for updates every once in a while and install them as soon as they are available. For apps that you use regularly, set up auto updation so that you can get updates as soon as possible.

    Uninstall the apps that you don’t use. If you can’t uninstall, disable them or remove all the permissions.

    Be vigilant on the permissions that apps require, especially if the apps request permissions that common sense says may not be required to work.

    If you want to see what permissions apps are using, go to Settings – Apps – Specific App – Permissions. You can remove the permissions retroactively, too. Most apps may stop working but some good apps will degrade gracefully.

    Mobile browsers and add-ons

    Browsing the web is a huge part of the mobile experience. The Chrome mobile browser is good but lacks a lot of features the Chrome Desktop browser has. For example, ad-blockers. The best replacement is Firefox mobile. It’s a great browser and also comes with standard add-ons. Some of the add-ons I use with Firefox mobile include uBlock Origin, an efficient ad-blocker that works just like the desktop version and is easy on bandwidth, and HttpsEverywhere that keeps your browsing session secure by shifting to HTTPS when available.

    Some of the add-ons I use with Firefox mobile are uBlock Origin, an efficient ad-blocker that works just like the desktop version and is easy on bandwidth, and HttpsEverywhere, which keeps your browsing session secure by shifting to HTTPS

    There are many more, take your time to explore and install.

    Password managers

    Password managers help you manage and use longer and difficult passwords without having to memorize them. There are many options to choose from. It’s better to choose one that works both on desktop and Mobile. LastPass, KeePass, and PasswordSafe are good options.

    Password managers can also be used as note-takers for sensitive information. Use password managers to save information like addresses, bank or credit card details etc.

    2FA or two-factor authentication

    Two-Factor Authentication, also known as 2FA, is an extra layer of security that requires not only the username and password but also something that only a user has with him/her. In most cases, it would be the phone.

    Install Google Authenticator on phone to start using 2FA with GMail and Facebook. Check the website TwoFactorAuth to get the list of all the services that support 2FA.

    Messaging

    Messaging services are the biggest communication tools on mobile. From SMS to WhatsApp to Facebook Messenger, there are a zillion options. Most of these claim to have end-to-end encryption but my suggestion, still, would be to check out something like the Signal app. It is available on both Android and iOS and is a good replacement for WhatsApp.
