India has over 1 billion mobile phone users, making it the second biggest market behind China and the market for mobile internet services is growing fast as only a third of phone users already have smartphones.
Over 100 million smartphones were sold in India last year and that number is expected to grow by over 25 per cent this year while network operators are investing heavily in providing 4G broadband.
In the last two months alone Bharti has spent about $1.2 billion on buying radio spectrum to expand its 4G service.
