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.
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.

the Face Unlock feature, which uses a picture of your face to unlock the screen. You
can also set a screen unlock pattern, a number-based PIN lock, or a text-based
password.
