Maybe there's some international carrier that locks the XT1053, and it just happens to work on TMobile?

If there is, I'm not sure who.

Do you have access to someone else who could try their Non-T-mobile SIM in your phone?

Is it possible the network unlock pin is actually a PUK or PUC Code? see also -> http://www.att.com/esupport/article....id=R7O-u149SD_

I've tried a few SIMs. My own TMobile and SIMPLE Mobile SIMs work. I've tried one h2o SIM and two AT&T SIMs, which all asked for an unlock PIN. So, I don't think it's a PUK/PUC issue.

There was an XT1053 from Mexico or something, but it wouldn't be locked to t-mobile. If anything I'd guess it was some sample phone sent to t-mobile for testing. The back cover may have been branded as such so someone swapped it out to hide that.
