Reliance Communication offers both GSM and CDMA mobile service in India. RCOM is the world's 15th largest mobile phone operator with over 150 million subscribers and India's 2nd largest telecom operator in India. However, I have also used Reliance GSM mobile service but I am not satisfied with its services. There is no doubt that the deals are quite beneficial and the tariffs are also low but the network coverage is not very satisfying.
