Using Cingular on MPx200 AT&T phone

[Guest jmk3d]

Sorry if this is posted elsewhere, please let me know.

I bought a MPx200 AT&T phone and unlocked it so I could use it with my Cingular SIM. All went well, and I am able to use the phone to make and receive calls/text msg but the network that it says it's on is AT&T Wireless (has triangle symbol, too -assuming that means roaming?). As much as I try, I can't get it to switch to the Cingular network. I have the 1900 band in my area (Nashville, TN), but even when I go to Preferred Networks to try to "Add" one of the Cingular networks it comes back with an error:

"Unable to save settings. Verify you have network coverage and that the setting is supported by your carrier."

Now, this is not a big deal for calls and txt msg, but I can't get on the internet either using the settings I found on this site for Cingular setup. I'm just guessing that I can't connect to Cingular GPRS because it's actually on the AT&T Network.

Am I anywhere close?

Hi...This is because Cingular and AT&T are the same companies now. Your phone will say roaming, but you won't be charged for it or anything...Whichever signal is stronger, I guess your phone will pick up. It terms of GPRS settings, try the AT&T settings...If that doesn't work, call up Cingular and tell them that you are mostly on the AT&T network and you need to use your GPRS. A friend of mine who has Cingular put his chip into my MPx200 and AT&T Wireless came up with the roaming triangular icon...In all, it's the same network, so don't worry. Hope this helps...

Yeah, that's kind of what I figured. But, the post for AT&T GPRS settings doesn't show much -no internet settings, just proxy. I guess I'll probably just have to call and get the run-around again.

But, the problem with not being on the Cingular network is that it seems like I have less coverage on the AT&T network. I had a Nokia 3595 that I could pick up Cingular in my hometown great, but AT&T doesn't pick up out there hardly at all. Or maybe it's just the phone.

Any thoughts on how to get it to work on Cingular network?

Thanks

**Edit to prev post: The only networks it shows on Preferred Networks under Settings/Telephony/Networks is AT&T and T-Mobile, even though I know there is Cingular Service out here.
