Help Anyone Unlock a One X to work on Tmobile??

You should be able to get the unlock code from AT&T if it is actually locked. They told me mine was already unlocked and that AT&T don't lock their phones (yeah I don't really buy it either)

I did basically the opposite. Unlocked a T Mobile HTC Sensation (just called TM and they emailed me the code), then tried an AT&T card with it. Everything worked fine except data. I was limited to 2G data since AT&T and TM use difference frequencies for their high speed data and the phone (hardware) wasn't set up for 3G or 4G outside of TM frequencies. So I got an AT&T One X

I suspect you'll run into the same issues, but doesn't hurt to try. If you get any crap from the CS rep, tell them you are going overseas and need to use a local TM sim card when there.

That's what the One X can do:

2G Network GSM 850 / 900 / 1800 / 1900
3G Network HSDPA 850 / 1900 / 2100
4G Network LTE 700 MHz Class 17 / 1700 / 2100

AT&T:
Voice: 850 (Band 5) / 1,900 (Band 2)
3G: 850 / 1,900
4G: Band 17 (700MHz)/AWS (1,700/2,100 MHz)

T-Mobile:
Voice: 1,900 / AWS
3G: AWS (1,700/2,100 MHz)/PCS (1900)
4G: AWS

Does that help? It certainly looks like your options are limited unfortunately. Could you get a Tmobile micro SIM to test?
