This is an unlocked GSM device that is compatible with most GSM carriers. You will want to contact your carrier to verify that it can configured to work on their network.

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

Yes it will work with AT&T; on their 3g network in any part of USA. Since this is an international phone data speeds will be lower than a locked phone to the network. You can use wi fi to connect for faster speeds.

Not sure I haven't been out of the US with mine. I assume it will just get an international plan. I've seen that plan available on the To Go Phone plans that I use with this phone. Call AT&T; and double check though.

Hello!The phone will work with US GSM carrier. But you better ask family mobile if their SIM cards will work with GSM unlocked phones.

If your phone is GSM (most likley it is) then it will work. There are plenty of SIM cards for sale that say AT&T; right on them. Why not get one of those? Then you can be sure.

Yes, AT&T; SIM card does work on this phone. This phone does not allow you to save your phone numbers on the SIM.

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

It should work with AT&T.; I've used mine with T-Mobile. Verizon phones don't have SIM cards, and, I don't believe are GSM.

It isn't a phone intended for the US market, mine works fine on AT&T; in the US. I have not tried to use mine out of the US. The unlocked 720 should work for you anywhere on a GSM network so long as the frequency is supported by the 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!
