Will SMT5600/SP3 work with Cingular, NOT AT&T SIM?

I recently purchased the Audiovox SMT5600 which, of course, is the same thing as the i-mate SP3. I was told, however, that I would have to use an AT&T SIM card with it and not a Cingular SIM card. They said it wouldn't even recognize a Cingular SIM card because Cingular SIM cards are 64 bit and AT&T SIM cards are 32 bit.

Anyway, the real problem is this. I live in Charlotte, NC. When Cingular merged with AT&T, they had to sell some of the AT&T markets to regional carrier. In our case this was a carrier called Suncom. The old AT&T network's coverage here stinks! However, the Cingular coverage is pretty good. I was told that I would get moved over to Suncom and, thus, be stuck on a crappy network.

Is there anyway that I can get this phone to work on the Cingular network instead? If so, what would I need to do to make it work?

You probably need to call Cingular again and speak to someone else :D

The phone will work fine with a Cingular SIM but the phone itself may be SIM locked to AT&T so you will need to get it SIM unlocked first. You could do this online by paying for the unlock code but you should also be able to get the code from AT&T if you explain that you wish to change to a Cingular SIM.

You could also try going into a Cingular shop and see if they can help you progress it through Cingular.

The Cingular store will be worthless in terms of help. I was in your same situation...bought the phone on ATT. Two weeks later, I migrated to Cingular. I paid to unlock the phone, removed all the ATT branding, and put in my Cingular 64K SIM card. The phone works flawlessly.

Do you still get ATT and a roaming indication? When I look at the available networks in the phone (when trying to go manual) it only shows Tmobile and ATT (Salt Lake City area).

Jimax,

How did you remove the ATT branding? I also bought the phone using Cingular service. I need to find out if there is a way to customize the main menu and remove any reference to mMode and its default link such as Sports, Entertainment, News and Search.

I have data services subscription with cingular and wanted to integrate my phone with Cingular Media service. Any idea how I can do it.

Help!
