The tower map or SIM issue has nothing to do with the technologies per se. SIM can be added to CDMA phones if so choose the carrier. China has both GSM and CDMA carriers. I believe the CDMA carrier chose to put SIM (or perhaps it is called by another name) in the CDMA phones too. |
Yeah, on CDMA it's not a SIM card, but a RUIM card. I really wish CDMA carriers used them here. CDMA has no chance of prevailing unless the rest of the world adopts it. As long as Europe is exclusively GSM, and the USA is half GSM, with Canada moving to mostly GSM, CDMA is going to be like the betamax of wireless technologies.
