The basic difference between GSM and CDMA is that the GSM is a SIM specific i.e. a mobile phone is identified in the network by the removable SIM inserted in that phone. On the other hand, in CDMA the network identifies a handset by the information stored in the internal memory and hence, its handset specific.
