The Telecom Regulatory Authority of India (TRAI) said that since the launch of cellular telephony, India added 4.5 million users in a month thus matching the "add-on" rate of China. China which currently has 388 million cell phone users, added only 43 million in the first 11 years compared to India's 76 million. TRAI said the average call rate in India is Rs.2.5 compared to China's Rs.3.5 a minute. It also pointed out the increased competition is decreasing the average revenue per subscriber to Rs. 344 a quarter for GSM and Rs. 244 a quarter for CDMA. Their study showed that a vast majority of the users used cell phones for local calls.
