Another big hit by reliance after 13 years. speed is superb. Network is strong. no other mobile operator provide this type of fast speed in the budget price. some problem in calling that is because of other operators. but why worry it is totally free till 31 december 2016. I hope other companies co-operate with JIO in the call drop issue. But seriously JIO is true 4g. and another issue is customer care support, it takes 30 minutes to talk a custmer care @ 199. For a digital life choose JIO. truely indian company with trust of shree mukesh ambani(richest man of india). love JIO. jai hind
