Mukesh Ambani on Thursday broke open the widely-awaited details of his Reliance Jio venture, billed as the country’s largest 4G network. Reliance Industries Limited (RIL) Chairman Mukesh Ambani on Thursday laid out his plans to unveil a 4G mobile network in the country, including making all domestic voice calls and roaming free, while asserting that data would be priced well below its competitors. Reliance Jio services have been on a trial run for a few months now, initially being limited to employees and then to those buying a Lyf smartphone from the company. From September 5, everyone will be able to access the service, which will still be free till the end of the year. Voice calls, meanwhile, will never be charged on the Jio service.

The data rates are also cheapest in the world, he said, announcing tariffs starting Rs 50 per GB or 5 paise per MB. The entire bouquet of apps will also be free till end of 2017. Reliance Jio’s data prices are roughly one-fifth of what customers have been charged so far - one gigabyte of data will cost Rs 50. For customers who use more than 75GB, the price will slide further to Rs 25 per GB. This, Ambani, said, take India from “Gandhigiri to data-giri.”It is further offering unlimited night LTE data for plans starting at Rs 499 onwards, along with unlimited national and local SMS. Starting Monday, any cell phone user, including those with smartphones as cheap as Rs. 2,999, will be able to sample all Jio services – including its library of movies and music - for free. The offer ends on December 31.
