BlackBerry GSM vs BlackBerry CDMA

Several GSM and CDMA based operators are currently in the process of applying for BlackBerry service in Indonesia. In the future, Indonesia will be covered by both GSM and CDMA BlackBerry. The challenge would be harder, however, for CDMA based operators because the number of handsets supporting BlackBerry is limited. It will be more profitable if the BlackBerry CDMA operators provide the dual network, supported by BlackBerry Roaming between the CDMA and GSM operators, in both the domestic and international network./ Seluler, pg 108
