Bharti Airtel Ltd.

Microsoft India is planning to sign a 4G data-bundling pact with India's No 1 carrier Bharti Airtel to encourage the latter's customers to buy the recently launched Lumia 4G smartphones. The 4G data-bundling pact will be extended to the more affordable Lumia 550, a 4G smartphone slated for launch in India around Christmas time. The Windows 10 device works only on a single 4G band (1800 Mhz) and is likely to be priced below Rs 10,000.

Bharti Airtel is a leading integrated telecommunications company with operations in 20 countries across Asia and Africa. The company ranks amongst the top 5 mobile service providers globally in terms of subscribers.
