Is it locked to a US network? If so, request an unlock code from them.

Consult your own network first, to make sure that the phone is enabled for the right radio frequencies.

They have checked and all is ok. Yes its from T-Mobile.

Have your uncle contact T-Mobile SIM Unlocking for the unlocking code (assuming the phone is still on its TMobile plan - it has to be to get the unlock code).
