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 which number you want to place
outgoing communication from. Before you can use both SIM cards, you need to enable
them and select which SIM card 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

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