I wish I could tell you but I do not know what AT&T phones it might or might not work in. I only know the it seams to work OK in my Vtech phone for now. The big question is for how long. Sorry!

No. This phone is verizon locked. Another customer said it didn't work with AT&T.; Hope that helps.

Yeap, it works on any at&t; phone or unlocked phone. If yours it's unlocked than the answer is yes.

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

It may not work with AT&T;, this phone does not have a Sim slot but if it descent require a Sim it should work.

Yes, you can use your At&t sim card in it. My works perfect with any sim card. Just make sure the phone is unlock.

Yes, it does. It was no problem working on AT&T. I will also recommend you to browse through Amazon feedback on how to configure the MMS and Web browser settings as AT&T will not be helpful in assisting you on an older outdated model. You search for Nokia C3-00 mobile phone and in the feedback "Nokia C3-00 Cell Phone - Awesome Product!!, May 23, 2011" you will get info on how to do AT&T Web & MMS configuration. However, as I wrote in my review, my honest opinion is to avoid this model as invariably the chances your touchscreen will malfunction are very high.

I'm not sure. It works with at&t.; But the downloading and internet is slow on this phone.

No, this works in any phone that takes a FULL SIZE SIM card (it needs to be cut to fit into the iPhone 4)and is on the AT&T network or unlocked.

Yes. It works with a Sim card. Actually says AT&T; when booting up. I use with consumer cellular.

No! This phone is not compatible with AT&T; as of September 2014. They will come out with a new phone, a 3G phone that works with AT&T;, until then this phone only works with AT&T; if you have an existing 2G SIM card. You can't get new service with them.

I ordered one a month ago and it worked on AT&T; with my micro SIM card. It does not however have any SD slots, it does come with 32 gigabytes of storage and about 30 of it is useable.

As a customer who bought this, I would think that you can put sim card in it and it should work. I did put my at&t; sim card in the one I bought and no problem. To be sure, you might want to ask the seller.

No, but the phone didn't work properly with sound. Purchased a phone direct from At&t;

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

It should, it works on AT&T service and I have used both locked ATT and unlocked phones and it has worked fine. Data some times needs configuration, and I think there is an app that makes it easier.
