Not necessarily....... there are CDMA handsets which make use of SIM (
called R-UIM) . Thats Removable User Identity Module for you. They
cannot be used in all CDMA handsets but only in RUIM handsets which
provide slot for the SIM.
The advantage of this is that a subscriber can log on to GSM as well as
CDMA networks by his choice.
