Finding the identification number of your device
Your device has a unique ID (identification) number. On your device, 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 and need 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.
To view your IMEI number on the label tray
1
Detach the memory card slot cover.
2
If a memory card is inserted in your device, unmount the memory card or turn off
the device, then remove the memory card.
3
Insert the tip of an unfolded paper clip (or a similar object with a long, fine tip) into
the groove in the label tray and then drag out the tray. The IMEI number is
displayed on the tray.
For detailed information about how to remove the memory card, see
