screen. The phone will automatically prompt you enter the old PIN code and ask to enter a new PIN code
twice. The phone will then prompt you that the change was successful. If you enter the PIN incorrectly
three times, the SIM and PIN codes will be automatically locked. You will need the PUK code to unlock the
