How do I change the PIN code of my SIM card?
You can always change your PIN code to one that is easier to remember.
Make the following combination on your mobile:
**04*old PIN code*new PIN code*new PIN code#
Your new PIN code is active immediately.
If you enter the wrong PIN code 3 times, your SIM card will be blocked automatically. You can unlock it by typing your PUK code.
