The telecom subscriber base fell to 944.81 million in July from 965.52 million a month ago, the first ever decline in the country.
The July subscriber base report released by Telecom Regulatory Authority of India (TRAI) shows that overall telecom user base of the country dropped by 20.71 million subscribers over June.
The decline in total subscriber base was led by the wireless segment where users declined by 20.61 million.
The biggest loss in user base came from Reliance Communications which lost 20.48 million users, followed by Tata Teleservices, Uninor, Videocon, Loop and MTNL.
RCom said the drop was due to removal of inactive customers from its user base.
The total subscriber base of RCom declined to around 134 million in July from over 154 million in June.
Tata Teleservices lost over 2.4 million wireless customers, Uninor lost over one million subscribers, and Videocon lost 0.41 million.
