TDMA / CDMA dont use SIM, only GSM does. THAT is where I see the problem... would a TDMA phone from TracFone work on Net10, which is just resold Cingular GSM.... Emailing these people would definitely not help, those people have no idea what theyre talking about. But some of the old TracFone TDMA phones on Net10 would be awesome.
I found it hard, its hard to find.. oh well, whatever, nevermind.
