IMEI uses all phone brands that support GSM signals. IMEI is used to indicate your device in operator networks. If you lose your device or someone stole it, by imei you can report to police and to your network so they can add your imei to a blacklist base. Also via IMEI you can apple check warranty on our website, or iCloud status check and iphone imei number check .

There is 2 options what you can do:

Option 1:
Turn OFF and then turn ON your phone. (before doing it, connect the device to wi-fi).
After that, input the sim card of your carrier. If you still get the message "sim card is not supported", then you need to do Option 2.

Option 2:
Restore the device via iTunes to the factory settings (don't forget to make backup).
After that, input the sim card of your carrier.

For some services we provide sim-unlocking without re-lock warranty, BUT we always indicate it in the services details. So if you use this service, and after some time the device will be re-locked, then there is NO REFUND.

You can find the model number in settings->general->about - Model number.
