Finding the identification number of your device
Your device has a unique ID (identification) number. In 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.
For devices with two SIM cards, there are two IMEI numbers, one for each SIM card slot.
