card is protected.

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.

Setting a screen lock

There are several ways to lock the screen on your device. For example, you can use

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.
It is very important that you remember your screen unlock pattern, PIN or password. If

you forget this information, it may not be possible to restore important data such as

contacts and messages. Refer to Sony customer support for more information.
