This case is for the Samsung Galaxy S3 phone no matter who your service is through.

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.

As I understood the AT&T; customer service person, it is compatible with those systems. I asked because my sister has the panasonic.

I have mine on aio.com which leases off of at&t;, so it should work for at&t;

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.

Will not support AT&T; LTE. But it will support Verizon. AT&T; uses different frequencies for LTE.

Hi If you have a single Sim card. The thing to do is call AT&T; and ask them if your card will work with this phone.

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.

It works with T-mobile definitely. Please check AT&T;'s frequency to make sure it will work.

I use it with VOIP, but not AT&T. However, I would think it should work fine.

I am not so sure. When I bought it, I had to have it unlocked from AT&T, check it to make sure it is unlocked.

It should be since it's the same frequency AT&T; uses and is unblocked. You could double check with the seller.
