Using multiple SIM cards
Your device works with either one or two SIM cards inserted. You get incoming
communication to both SIM cards and you can select from which number you want
to place outgoing communication. Before you can use both SIM cards, you need to
enable them and select the SIM card that will handle data traffic.
You can forward calls that come in on SIM card 1 to SIM card 2 when SIM card 1 is
unreachable, and vice versa. This function is called Dual SIM reachability. You must
enable it manually. See
Forwarding calls on page 85.

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.
For devices with two SIM cards, there are two IMEI numbers, one for each SIM card slot.
