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 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 service provider.
