As long as you have a Samsung Galaxy s3, this item should fit. I do not have AT&T; as a carrier.

As long as its a galaxy s3 it should work. We have a Verizon s3 and a straight talk s3 and it fits both.

I cannot confirm whether or not it is compatible but I can assure you that there is a slight difference between the Int'l One X and the AT&T version. I suggest you do not take the chance and specifically look for the AT&T replacement part

This unit will work with most AT&T; modems but to be sure we would need to know the model of your modem. Thanks, WirelessNWifi

Works with T-mobile for sure. Haven't tried AT&T;, but it should work. I can try it out later if you really want me to.

Don't know, but it wasn't compatible with Verizon. Contact your AT&T store with the model number and they can tell you.

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

Will work with at&t.; I think that means it takes a micro SIM card. And no, it does not have a micro SD slot.

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.

Yes, it can be used with AT&T; since it works on 1900 y 850 MHz frecuencies. Although I do suggest asking directly at AT&T;

Dear Customer, Thanks for your interest in our items. Yes, this is an unlocked phone compatible with At&t. NOTE: Unlocked phones are not yet programmed for any network. In order to access the internet and use multimedia messages, you will need to program the phone according to your carrier. We have instructions for AT&T and T-Mobile (USA only).
