SIM card protection

The SIM card lock only protects your subscription. Your device will still work with a
new SIM card. If the SIM card lock is on, you have to enter a PIN (Personal Identity
Number). If you enter your PIN incorrectly more times than the maximum number of
attempts allowed, your SIM card will become blocked. You need to enter your PUK
(Personal Unblocking Key) and then a new PIN. Your PIN, PIN2 and PUK are supplied
by your network operator.
To enable the SIM card PIN lock
1 From the Home screen, tap
2 Find and tap Settings > Security > Set up SIM card lock > Lock SIM card.
3 Enter the SIM card PIN and tap OK.

To unlock a locked SIM card

If you enter an incorrect PUK code too many times, the SIM card becomes locked. If this
happens, contact your service provider to get a new SIM card.
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.
