I am using relaince jio 4g sim card from 6 months ago.
4G Speed-
The 4g speed of jio is very slow even if you compare any other operator 3g and jio4g the 3g network gives you better speed.
Network strength-
The networ strength is full in my are bt it cant able to give me good experience of 4g.
Voice calling-
The voice calling function on this network is very poor you cant able to call for 1 min.
It always says that all lines on this route are busy
Which is very shameful for jio
