Introduction
Reliance Jio Info COMM Limited, popularly known as Jio, is an Indian mobile network operator launched
commercially on September 5, 2016. Owned by Reliance Industries and headquartered in Mumbai, Maharashtra, it
operates a national Long-Term Evolution (LTE) network with coverage across all 22 telecom circles. Jio does not
offer 2G or 3G service, and instead uses Voice over LTE (VoLTE) to provide voice service on its network. The
launch of Reliance Jio has caused a revolution in the telecom industry. Now, Jio claims to be the world’s largest
data network, based on mobile data consumption.
According to the Telecom Regulatory Authority of India (TRAI), as of February 2019, there are 1.17 billion
mobile-phone subscriptions in India, an increase of roughly 140 million subscriptions since August 2016—the
month before Jio launched. The growth is especially pronounced in rural areas, where there are now over 500
million wireless subscriptions, roughly 80 million more than there were before the company formally began its
operations. As more Indians gain phone subscriptions, more are coming online. A 2017 report by the Internet and
Mobile Association of India estimated that nearly 50 million Indians gained internet access between December
2016 and December 2017, allowing many of them to surf the web, send WhatsApp messages and stream videos for
the first time.
