Can you put the global version on a US carrier?

If GSMArena is to be believed, the US model (RM-938) will support both AT&T and T-Mo's frequencies (2G, 3G, and LTE). I'm a little hesitant to believe it though because we've yet to ever see a pentaband HSPA+ Windows Phone device. I wouldn't be surprised if GSMArena just filled it in with all possible freqs and will edit when they get official confirmation.

So I can take this RM-937 - global version and bring it to AT&T with ZERO issues. Before switching to WP, I was able to bring an unlocked Singapore iPhone and use a ATT sim.

Usually the hardware is there but the firmware disables everything that not stinking AT&T.

Another option seems to be using an unlocked version of the RM-38. This is the latin america version and covers the same spectrum as the us version, with the addition of 1700 and 1900, which means it will cover tmobile's network perfectly. In addition it has 32gb storage and built in wireless charging. This seems to be the perfect solution for users who want the full-spec phone on tmobile

I was looking at that option myself because of the rumoured "slashed specs" of the ATT device. I have one question though. The 1520 is speced to be using a nano sim instead of a micro sim. Will that matter?

You mean can you buy an unlocked global version and use it on ATT's network ? yes

Have you done this before with a WP device?

Have you done this before with a WP device?

I have, sort of. I bought the Telstra version of the HTC HD2 with Windows Mobile 6. Australia uses one of the two bands that AT&T used for 3G. I just moved my SIM and it worked. AT&T was never told what device I had.

I do have a question out to our A&T Enterprise sales rep about using foreign phones with tethering. No answer yet.
