Yes. You simply take the SIM card from your old AT&T; phone and put it in this one. I picked this phone because it can be used overseas as well. It's working fine for both of my parents.

Yes you can. At&t; uses GSM service so yes you can travel with it. But like a previous answer, you will need to unlock it.

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

No, it´s AT&T; locked, but comes with a unlock code, so you can use with any operator without any problem.

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, unfortunately not. It plugs into the 3G MicroCell to help it get a GPS signal. A 3G microcell, along with a high speed Internet line will make your AT&T; phone work where you otherwise don't have cell signal. I imagine other carriers have similar devices.

Since it is an AT&T; phone, you don't need to have it unlocked to use on AT&T; prepay. Just put in a prepay simcard are you are good to go. And, no, the phone is not unlocked in that it can't be used on networks other than AT&T.;

I use it on Windows 8 with the Windows 7 fax program without any problems. I really don't know if the AT&T; internet would be a problem, but my guess is that if you can use your phone on this line, it should be ok.

You can use any cordless or wired phone. The product works flawlessly. and has renewed my faith in AT&T.;

Not sure you can. I couldn't do it with AT&T remote. Just follow the remote instructions & see if it can find the right code.

No! Ours didn't work well with AT&T;! I was supposed to be unlocked but didn't respond to several AT&T; features!
