In india after coming Jio all other companies has gone to biggest loss and they all companies are suffering from this problem. My experience with Jio is very nice I am using Joi from 8 months if I will say about network of Jio in metro cities and some other cities are normal like other company network but in some area like villages network is not able customer service is average charges and billing is too low I am enjoying with Jio. In Jio one time investment and then free to buffering internet, messaging, and calling so due to Jio price has reduced by other companies and they are also going in loss
