Jio come in mid month of 2016.
When it come it gives free unlimited net which gives 3gb net @1 mbps then 144 kbps.
It was great but jio has calling problem that time .
Than after dec it increase it time to march then it give only 1gb not 3 gb it also good .
Speed was great calling problem still.
But nowdays I feel that calling problem solve and signal also great compare to other one.
Many of companies say that they gives high speed but the problem was that either their pruce was high or theit 4g tower was not in the area like in my area their was no 4g tower of most of that company and the signal was weak compare to jio.
Jio was good according to rate signal calling ways .
It was great.
So, buy jio sim if you dont and subscribe to it prime offer and get 50 cashback 5 times First recharge on jio by jio money.
Thank you have a nice day evening night.
