Both RCom and Tata had shifted to
GSM after the government's dual technology policy, which allowed CDMA players to offer mobile services in the other space.
GSM was also the more popular form of mobile communication, as CDMA mobile phones came blocked with the SIM of the service provider, while there was no such thing in GSM mobiles.
At the time of GSM launch, both had said they'd continue to focus on their CDMA mobile services.
Tata Teleservices also has a partnership with Japan's NTT Docomo for their GSM venture.
