According to me, Reliance Jio is the best mobile operator in India. It comes with the plan of rs.399 under which there is unlimited talktime and data ( 1gb per day) for 3 months. In addition to this, it also comes with 100 sms per day. Data speed is very high as compared to other networks and it never loses its connection, no matter where you are, except where there are no mobile towers. No buffering . The best part is after you have finished your daily high speed 1gb , you can still work on the net as your data speed will be reduced to 128 kbps, but it will not be disconnected. This feature is not given by other mobile operators. I would recommend everyone to change their network operator to Reliance Jio.
