BSNL had provided awesome dataplans for us even before jio had stepped into the market.It has good cell reception but when it comes to reliability and speed the reputation of BSNL is not actually on the high note.
I find it really hard to finish almost 1gb of 3gb daily limit and that to the speed varies a lot between 0-200kbps
Online streaming of movies, cricket is difficult with this speed .
Upload speed lies between 0-20kbps
