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.
But it isn’t.
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 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.
Settings> Lock Screen and Security> Other security settings> SIM card lock> Lock SIM card> Change PIN> Restart Device
Remember this very clearly that if you entered the SIM PIN incorrectly for 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 the 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.
