Do the new att sim cards work in the cingular phones?

I am thinking that they dont, but has anyone tried this before?

Do the new att sim cards work in the cingular phones?
Yes it should perfectly. A at%26amp;t sim card should work in a Cingular phone. A sim card registers the phones Serial number to the network. If the serial number is in Cingulars system it should work........ Cingulars and at%26amp;t's sim cards register to the same towers.
Reply:when Cingular bought "old AT%26amp;T" it wouldn't unless the phone was unlocked because they were separate networks (though not for good reason - AT%26amp;T's GSM %26amp; phones could conceivably have been integrated into the Cingular network w/o changes). AT%26amp;T also had a TDMA network that couldn't be integrated. Report Abuse

Reply:Now they're just rebranding. This is similar to a person changing names when (s)he marries. The person doesn't change, just the name.





As a matter of fact, my old Cingular phone now says "AT%26amp;T" on the screen but works just the same with no updates. Report Abuse

Reply:Cingular is now.........THE NEW AT%26amp;T.





Well, that's what they said on my last bill.





I want my, I want my, I want SNET.
Reply:contact att and ask
