I believe that you can only use this phone with T-Mobile..on a prepaid plan. Not sure is AT&T; has a prepaid plan.

I don't use At&t; but yes it can At&t; if they offer Sim cards. You still can call them to enquire.

No. This is a GSM phone that requires a SIM card. Also, the one I received is only a tri-band GSM. You need a quad band to be guaranteed to work with T-Mobile and AT&T; in all areas of the US. I'm not able to use this phone with ATT in my home area.

Yes it uses the straight Talk sim cards, however it will use the att towers with the straight talk sim.

The model number is LT30p Xperia T. I'm not familiar with the AT&T version because I got the unlocked phone, meaning I can use any network.

Does not work with my AT&T sim. Phone only seems to detect T-Mobile, but I have not tried with a T-Mobile sim

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.

I use my phone on a GSM network in Jamaica and it works perfectly. AT&T is GSM so it should work.

While I cannot guarantee anything, t-mobile and AT&T; use the same types of connection, so you should just need the right SIM card.

No this is a Tracfone. My Tracfone is running on AT&T;'s network in my area.

No, this is a Sprint powered tablet that uses CDMA technology. It does not use a SIM card like AT&T and T-Mobile.

This phone does not get 3G on T-Mobile network. It's better on AT&T network.
