Have you tried an AT&T SIM? Maybe it will work without an unlock, not the full service until the number is ported.
I had that happen once with T-Mobile with a 521. FWIW, I got on chat and asked to talk to a supervisor who was able to look at the account to see the code they supposedly sent me and gave it to me. He said he wasn't supposed to do that, so may not be a 100% sure thing. They also counted their failed attempts as separate unlockings and I had to fight with them months later when they claimed I'd used up my yearly allocation of unlocks.What a Nightmare!
I've been trying to for a week to get T-Mobile to send my Brother an unlock code for his Lumia 640. Was told he has met TM's requirements and they have said three times that the code has been sent out and to wait up to 24 hours but nothing happens. I have checked my ISP Graymail box to see if it got caught there & have double checked with TM to see if they sent it to the correct email address.
T-Mobile Customer Service is a Joke :eck:
