Tata Teleservices Ltd has become the country's fourth largest wireless telecom operator with 77 million subscribers at the end of August, according to official figures.
The company added 2.1 million new wireless subscribers in the month, thereby overtaking state-run BSNL. It continues to trail Airtel, Vodafone and Reliance, which have over 100 million wireless subscribers each.
According to figures released by the Telecommunications Regulatory Authority of India (TRAI), Bharti Airtel, the country's largest telecom operator continues to have the largest number of wireless subscribers, with 139 million at the end of July. Reliance Communications is the second largest wireless operator with 113 million users, and Vodafone-Essar comes third with 111 million users.
BSNL is now relegated to fifth place with 73.7 million subscribers.
A TTSL statement said, ''The crossing of the 75-million-subscribers' mark by Tata Teleservices Ld and Tata Teleservices (Maharashtra) Ltd is all the more commendable as both entities have shown a subscriber growth rate of more than 100 per cent in the last 12 months - from 38 million subscribers in July 2009''.
TTSL started offering CDMA mobile services in 2005 and received permission for dual technology (GSM and CDMA) in late 2007.
