The rating agency, however, said aggressive bidding in the upcoming spectrum auction and emergence of competition from Reliance Jio, which could substantially slash data tariffs, are concerns that could lead to an outlook review in the future.
"...Maintained a stable outlook on the telecommunications services sector for FY16 on market consolidation leading to better pricing power, as well as higher data consumption and improved the financial profiles of operators," India Ratings said.
India Ratings said it believes India's low Internet penetration and increasing acceptance of e-commerce and social media shall drive a surge in data consumption.
"This increasing user base and rising data volumes will further provide the traction for data revenue growth in FY16," it said.

Increase in competition in the voice space leading to lower average revenue per minute or disruption of the data market by new entrants thus affecting the blended average revenue per user could lead to the outlook being revised to negative on profitability concerns.
The agency said margins of the telecom operators in India have been supported by increasing voice tariffs and growing data consumption.
With the exit of many regional players, India Ratings said, telecom operators are left with fewer opportunities for further market consolidation.
"However, existing smaller/regional players may look to monetise their holdings given the limited scope of their operations," it said.
India Ratings believes that the large operators shall continue to dominate the industry with better pricing power while the regional players seem to be awaiting clarity on M&A or spectrum trading guidelines to weigh their exit options.
