SIM card protection
You can lock and unlock each SIM card that you use in your device with a PIN
(Personal Identification Number). When a SIM card is locked, the subscription linked
to the card is protected against misuse, meaning that you have to enter a PIN every
time you start your device.
If you enter the PIN incorrectly too many times, your SIM card will get blocked. You
then need to enter your PUK (Personal Unblocking Key) and a new PIN. Your PIN and
PUK are supplied by your network operator.
