No it's not fully compatible with AT&T.; that's why I had to return it. I only could use it for the basic like calls and text and not internet. That's been over an year ago tho so who knows. Not sure about Tmobile.

My phone would. It was unlocked to work with any US carrier. I have T-Mobile through Walmart Family Mobile. But if I wanted to switch to ATT, I can do so with no problems because it is factory unlocked.

Mine works with att. You should check out their website. For me it's been way worth it.

Sorry I don't know the answer to that, since I've got the ATT version of the phone. I would think so, but can't sy for sure.

It may not work with AT&T;, this phone does not have a Sim slot but if it descent require a Sim it should work.

It should work, but you might have data reception issues since one of the frequencies used by AT&T for data (850 MHz) isn't supported by this phone.

The phone is unlocked so... It should work with your AT&T sim card (3G - HSDPA 850 / 1900 / 2100). My dad used the phone in Venezuela with Movistar (HSDPA 1900) without problems at all!

Yes. But it is fully functional only on AT&T; platform. We returned ours as it was not compatible w/provider.

the 3G network of AT&T is WCDMA, and this phone support WCDMA, so it will still work with your SIM card

It does not appear to e compatible - check the ATT phone store online to find match phones and headsets. Many vendors on Amazon do not provide that info, but ATT does

As staed, compatible with 2G & 3G 800/850/900/1900/2100 & 4G LTE 800/900/1800/2600 network simcards worldwide. This means 2g & 3g with att is ok, not 4g, as AT&T uses different 4G. With regard to your Mexican network, see if your network uses GSM Types that the phone is compatible, then should be fine. Please check with your network provider. Thank you. KICKmobiles
