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.
