Yeah, you are right, Scot.
Plz kindly tell me, which site or documents about roaming between GSM and CDMA I have to refer to?
Do u know any information concerning to WCDMA and CDMA 2000? or do u know any related material?
Is it true that both WCDMA and CDMA 2000 are 3G?
Does the subscriber of WCDMA network use SIM card?
Thank you
