SIM card protection
You can lock and unlock each SIM card that you use in your device with a PIN
(Personal Identity 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 more times than the maximum number of attempts
allowed, your SIM card will become 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.
