What cell phones can I use with the old AT&T Wireless network?

Question by JMan: What cell phones can I use with the old AT&T Wireless network?
I have a great AT&T Charter GSM plan ($ 99 unlimited calls, free long distance, free roaming) which I don’t want to lose but I don’t like my phone. I’m currently using a Siemens S46 and have bought replacement phones over the years but would like to switch. What other phones can I use that would be compatible with the old, pre-Cingular- AT&T Wireless GSM network? Can I just buy a new phone, and if so for which network? I see people posting questions about “unlocking” phones – is that necessary if I buy a new phone and if so how do I go about doing that? Are there any licensing issues with AT&T using one of these phones? Thanks in advance for your help.

A Cingular phone should work since Cingular and AT&T are the same network.

  1. You are much better of buying and UNBRANDED QUAD BAND as opposed to unlocked phone. One that has not be produced and/or locked onto any specific carrier (Cingular, T-Mobile, etc) I got a quad band Motorola Rizr and it works perfectly. If you just want to make and receive calls and do simple texting it is the way to go. If you are interested in Multimedia Messages and Internet you may have to contact Cingular or search the Internet on how to program the phone since the phone was never programed for those options.

    I was told an unlocked Cingular phone may work with other GSM sim cards but not AT&T. Possibly a way to make us AT&T hold outs switch. You can get them from the manufacturer or on ebay. I tried an unlocked Cingular Samsung phone and my At&T sim would not work.
