I am not sure you can, but it should work with virtually any SIM card. Do you have an old one to try from a different carrier than the one it is locked to?

What code did you enter? Entering ##7820# into the dialer like you're making a phone call should bring the menu up. Inserting an AT&T SIM card or MVNO (Net10, cricket, straight talk, etc.) that uses AT&T's network should also make the menu come up.

pls my ime is <deleted by moderator> and i did not receive my 20 digit code

 

[RumoredNow]

The unlock code comes from the carrier. Contact T-Mobile US for that code.

Then use the ##7820# to see the unlock entry screen.
