What is a PUK code?
PUK stands for Personal Unblocking Code. This acts as a security feature on your mobile. To protect you in the event of theft, the SIM card is immediately locked if someone keys in three different incorrect PIN codes in succession. This also applies if you absent-mindedly enter an incorrect PIN code three times in a row. The message “PIN locked” will appear on the screen. In this event, you can fall back on the PUK code, which comprises eight digits. Enter this code in order to unlock your mobile phone, and then follow the instructions on the screen. Should a person give an incorrect PUK code ten times in a row, the card will be irrevocably cancelled. Do not store your PUK code on your mobile phone. In particular, don’t write them on the back of your SIM card!
