I don't know because mine stopped working (after about 3 months) before 4G became available here.

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.

I don't think so...it's a Verizon phone so am quite sure it doesn't work with the AT&T; plan!

Yes, this phone works with AT&T and T-Mobil for 2G service(phone call +GPRS/EDGE Data) . For 3G service, it works only on T-Mobil.

Yes, it does work AT&T. I have AT&T now and so far I haven't had any problems - however, when you get away from an AT&T coverage area it is far easier to lose your signal. If you do a lot of traveling this phone may not be for you.

If you use at&t; you can put 3g or 4g sim cards in it and it will work. AT&T; just started giving the cards for free just ask. They won't offer it to you. So remember to ask. I hope this helps I love mine.

It works with both 3G and 4G. You need to correctly set the APNs if the phone doesn't do it automatically. There are some tutorial on the internet and on youtube.

It for sure works with 3G.... I don't have 4G in my area so can't say for sure about that.

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 it work with AT&T; and T Mobile:) and any service provider who is operating on their network as well as for GSM 850/900/1800/1900 frequency

Yes. It will work on any AT&T; GSM network. Be aware that the device is only rated for 3G use. (May very by location) I would advise you to check the straight talk website. Hope this answered any questions you may have.

It will work with an AT&T; iPhone 4 but it will need to be unlocked which is really easy to do but you can talk and text when it is not unlocked but it needs to be unlocked to use data

No. Even tho it is unlocked it may/may not work with 4g since that is an exclusive Verizon phone. I have att and my 4g doesn't work, so I called about it and that's what was told to me. There is a possibility that you get one that will work but chances are that you won't.

It will work with AT&T;, T Mobile, or metro,etc. As long as the network has GSM (sim card)

Yes I have this phone and use it with straight talk on the AT&T; network. You can also use it on the T-Mobile network through straight talk. 4g LTE work great on AT&T.; Don't know if LTE works on T-Mobile but in theory it should because they use the same frequency range in the USA. Hope this helps.
