The subscriber growth was forecast to outperform the regional and global averages over the coming years. India was positioning itself as the world's second-largest mobile market after China. "India is a unique mobile market and one where the mobile ecosystem is playing a hugely influential role in transforming the lives of its citizens, and driving economic growth," said Alex Sinclair, acting director general and chief technology officer at the GSMA.

“Continuous availability of spectrum has played a big role in India. India is an extremely competitive market," said Alasdair Grant, head of Asia, GSMA. The report said India had 453 million unique mobile subscribers at the end of 2014. This is forecast to cross the 500 million mark by the end of this year.

Another 250 million subscribers would be added by 2020 to reach 734 million, accounting for almost half of all the subscriber growth expected in the Asia Pacific region in this period. The report stated that India's mobile industry was also a key driver of economic growth and job creation.
