IMEI number
Every device has a unique IMEI (International Mobile Equipment Identity) number. You
should keep a copy of this number. If your device is stolen, your network provider can
use your IMEI number to stop the device from accessing the network in your country.
To view your IMEI number
• Turn off your phone, then remove the battery cover and battery to view your IMEI
number.
• Open the phone dialer on your device and enter *#06#*.
To view your IMEI number in the device
1 From your Home screen, tap
2 Find and tap Settings > About phone > Status.

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.
