Since from last 2 month I am using reliance Jio and its quite good. at the inishal stage it was having some problem related to network issue and calling problem. but from last month I am very much happy with the reliance jio. Reliance Jio is developing day by day its customers are growing very fast in every city they have their customer service office. now again 3 month have been increased its free till 31st march 2017. lets see the charges of reliance jio after that. only the disadvantage is that it is not spread all over the country in rural area we cant fing the network for reliance jio.
