IMEI number

Every device has a unique IMEI (International Mobile Equipment Identity) number.
You should keep a copy of this number. If your device is stolen, your network
provider can use your IMEI number to stop the device from accessing the network in
your country.
To view your IMEI number
1Remove the cover of the memory card and micro SIM card slots.
2Insert a fingernail, or a sharp object such as a pen, into the hole in the label
tray, then drag the tray outwards to view the IMEI number.
You can also open the phone dialer on your device and enter *#06#* to view the IMEI number.
