Bharti Airtel Ltd.

The country’s operators dished out more than 262 million cell phone connections in 2010, taking the total number of mobile subscriptions to more than 752 million, but only 70% of these are active customers. New telcos such as Etisalat DB, STel, HFCL, Videocon, Uninor, Tata DoCoMo (GSM) and Sistema Shyam have less than 50% active customers, in sharp contrast to the national average of 70%.

Bharti Airtel had about 92% active customers, while Idea Cellular had a little over 90% followed by Vodafone Essar at 76%, compared to 47-50% for Tata (GSM and CDMA) and 66-68% for Reliance Communications.
