I am totally fade up with reliance JIO data speed, it is worst and the average speed I am getting now is 10-20 kb/s which is worst, even 2g gives more speed than this 4g jio sim. Also there is big problem when you call on any other mobile operator other than Reliance or its own network JIO 4g, it tells that network is busy and you have to dial multiple time to call a number it is worst in the case of Airtel, Vodafone, Idea. So I request to JIO to kindly resolve these problem as soon as possible.
still fetching above problems I recommend to take it and use it till it is free because none of mobile operator provides free calling or free data so I recommend to students to use it but business man should not use it because sevice provided by jio is very poor and it may affect his business.
