When I started researching this story, I knew I needed to visit a place with no internet access.

"We are committed to connecting everyone and everything, everywhere." For Gorakh Dan, Jio has opened up a whole new world.

The 26-year-old works as a stone supplier in the city of Jaisalmer, about 40 miles from Devi's village.

There's one bus a day that passes through, the only connection to the nearest city more than 50 miles away. Otherwise this phone is just lying there useless." Like nearly 900 million people in India, Devi has never used a smartphone or accessed the internet.

She needs to climb onto the roof of her house to catch a couple of bars of cell service so she can call her children and relatives. The race to bring those millions online, adding to more than 500 million Indians already connected to the internet, is being contested by the biggest global names in tech.

amna Devi got her first cellphone about a year ago.

It's one of those with a tiny screen and a numbered keypad, the kind that are becoming increasingly rare in the age of Android and the i Phone.

He got a Jio SIM card five months ago and then purchased his first smartphone, a Nokia, for about 5,000 rupees ().

Dan is now obsessed with Whats App, which counts India as its biggest market, and You Tube.

That triggered a price war with other mobile providers slashing their rates dramatically.
