Mobile connections in India will grow to 880 million in 2015, a five  percent increase from 837 million connections in 2014, according to Gartner.

Spending (in constant U.S. dollars) on mobile services will grow four percent to reach $21.4 billion in 2015, driven by mobile Internet services.

Spending on mobile services will be driven by data services, which is expected to grow 15 percent to reach $6.5 billion in 2015.

A large chunk of this growth will be driven by the increasing use of cellular services on data-centric devices, such as tablets and notebooks, through either embedded cellular modems or USB sticks, Gartner believes.
