I have been using jio Sim for a long time at first its service was very good internet speed was good but day by day the internet speed is decreasing as the number of subscribers has increased and the rate of recharge has increased a lot, so to me it is very profitable. It does not seem to have to be recharged separately to make calls to other networks This is not a very good idea to me, where other operators are offering a lot of good benefits at low recharge at very low cost.
