To change the PIN code, click Change SIM PIN. Then, you’ll have to input the current code, followed by the new code – twice, so that you’re sure it’s verified.

    this kind of tips are basic, and every body knows how to do this, do not post such type of posts, like how to clear android market history, how to check your android software version.

      Thanks for reading pakwing!. Not ALL of our readers know how to do everything on Android. We have readers who are beginners and experts alike. We want to accommodate everyone.

    • Bogdan

      I actually wrote this tip after a couple of people asked me how to do it, so I guess not everybody knows how to do these things. Or maybe some people are just too lazy to look. In both cases, it could be helpful.

    • Bipbip

      You aren’t right. I for one have forgotten how to remove the PIN-code request, and after a Google search found this post very useful.

      • Bogdan Bele

        Thanks! Great to hear that!

    • spamless

      I have managed IT departments. I didn’t know how to do this, though I did believe I would be able to figure it out on my own inside of a minute. Nevertheless, it made me feel better about it to check ahead of time. (I’m visiting an elderly friend who can no longer remember his SIM PIN.) Don’t be such a putz, Pakwing. Some of us grew up before there were smartphones. In my case, before there were four-function calculators. (Wanna have a go with my slide rule?)

    how to unlock it? i tried and it wont let me uncheck the box :/

    • Adi

      Same with mine Kai, my android suddenly locked sim card. Any sim card cannot be used to the android, and the simcard which locked in the android can be used in other phone.
      Please, who ever know how to solve this problem ?

      • Bogdan Bele

        If the card works in another phone, it must be something related to your Android device. You could try to master reset it and try after that (but you’ll lose all data in it).

        • Mark

          I’ve got the same problem and tried your suggestion but it didn’t work

    my tablet sim card lock setting need me to key in the old sim pin number, but i totally forgot and can’t remember the number before i can change the sim card lock to a new number,
    can you show me the correct matter to track my old sim pin to correct it?

    • Bogdan Bele

      Is the SIM locked with a PUK? You can get that from your mobile carrier if you enter a wrong PIN 3 times.

  4. Name

    Thanks dude, just googled it! useful info.

  5. marco

    I need to install a configuration message for the APN but it askes for a PIN.
    Is it the SIM PIN or what ? because whatever I insert, it doesn’t work.
    I also tried to remove the SIM PIN, to insert the old one, no way.

    • Bogdan Bele

      I honestly haven’t heard about anything like that before. Have you tried asking your carrier? Maybe it’s something related to that message.

      • marco

        I’ve read on the net that others had the same problem but didn’t find any solution. I’ll go to the shop and ask. When I bought the phone (Shengda SM-N900) all was ok, then I rooted it, installed some apps and started having problems with the phone calls, noisy. So I did a factory reset and from that moment I cannot send messages and cannot install configuration messages. I wanted to make a factory format but if I reboot the phone in download mode, it’s in Chinese and don’t understand a word.

  16. Dennis

    Thank you so much for your post! It’very useful! The last time I used mobile phones was about 10 years ago.. Now I have bought one again and man, it sure has changed a lot and there is so much to learn again :-)

  17. Mark

    My phone tells me my SIM PIN is incorrect when I try to disable the lock. I know it’s the right number as I can unlock the phone and I can change the number.
