­India's GSM networks added a record breaking 7.7 million net customers in October - reports the Cellular Operators' Association of India (COAI). The total GSM base now stands at 241.4 million as at the end of last month.

The figures however do not include the GSM subscriber base from Reliance Communications - which although a predominantly CDMA operator has a growing GSM base as well. Estimates from the Mobile World subscriber tracker report that the company ended September with around 9.2 million GSM subscribers.

That would bring India's total base to over 250 million GSM customers.

The Mobile World also estimates that the country has around 77 million CDMA users - bringing the whole country mobile user base to 318 million.

The country's largest operator, Bharti Airtel added 2.72 million new customers, while Vodafone Essar added a record 2.1 million new customers.
