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 that 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 network operator.

Finding the identification number of your device
Your device has a unique identification number. This number is referred to as the IMEI
(International Mobile Equipment Identity). You should keep a copy of this number.
You may require it, for example, when you access the Xperia™ Care support service
to register your device. Also, if your device is stolen, some network providers can use
this number to stop the device from accessing the network in your country or region.
