Introduction
Unlocking is useful if you want to bring your smartphone to a new carrier.
Make sure the phone will prompt and ask you for a network code when a different or non-supported network SIM card is inserted and the attempts counter is not 0 .
You must send 15-digit IMEI number (tape *#06# from the dial app to see it) and the original network provider.

            Power off your Nokia Lumia. 
- 
            Insert an unaccepted SIM card. 
- 
            Once the SIM Unlock box appears, provide the unique 20-digit unlock code that you received.

            That's all.
