Change the PIN code of your SIM card

Change the PIN code of your SIM card using a short code or via your mobile phone menu. For your security, avoid using obvious PIN codes such as 1111 or 1234.

  • Via a short code

    Type in the short code **04*Old PIN code*New PIN code*New PIN code# on your mobile phone and press the call key. Instead of Old PIN code, enter your current PIN code and instead of New PIN code, enter your new 4-digit PIN code. For example: **04*1234*1369*1369#

  • Via your mobile phone menu

    Go to Settings > Security > SIM card lock > Change PIN code. Enter your old PIN code first and then enter a new code of your choice. If your mobile phone has a different menu, please consult the manual of your device or the manufacturer’s website.

Did you forget your PIN code?
Enter a wrong PIN code three times. Your mobile will now ask for your PUK code. Enter the PUK code to unlock your SIM card. Afterwards you can choose a new PIN code.
