BSNL - Bharat Sanchar Nigam Limited

Bharat Sanchar Nigam Limited is India's state-owned telecommunications company headquartered in New Delhi. It is one of the largest provider of landline and broadband services in the country, with more than half of country's market share.

BSNL offers telecommunication services in 3 different categories: Landline, Broadband and Mobile. The company offers GSM mobile services under the brand name "Cellone", and fixed broadband services under the brand name "Dataone".

BSNL is one of the oldest telecommunications company in India and has great availability from a big city to even the smallest town of India. But, with the emerging competition in the telecommunication sector, the company's market share and revenue have been severely hit in the past few years.
