I use reliance jio from last 2.5 months in lyf water 7 mobile phone( price 9700) .phone is good stylish easy to carry.
at the time of calling it takes some time .but when call is connected .it gives good feeling .and my call is never drop before 30 minutes.in delhi ncr speed of internet is awsome.downloading, browsing, chatting all are fablous .but some problems related to net and calling faced in rural areas.
