Unfortunately, you cannot activate a TDMA phone w/ Cingular. Just like if you tried to activate an older Analog phone. Cingular no longer sells TDMA calling plans, the only customers who can use TDMA already have those plans setup. Also, can't use a former AT&T phone on Cingular. What model phone are you using?
I recently purchased a new "used" car with a TDMA cell phone. I would like to activate with current carrier which is Cingular. Customer service said no go.
I need recommendations on how to get this phone activated any way that I can. Cannot believe that my current carrier is unwilling to activate (based on 800 customer service/tech call).
Any help or suggestions would be greatly appreciated. Phone was recently on the AT&T network.
