Been using Jio since its launch.
Reliance jio is revolution in Indian Internet providing 4g net in the prise never before. We used to use 1 gb of data in a month but now use 1 gb per day.
Customer service is quite good and humble.
Speed of jio is quite good ( 1-2 mbps) but in area have no traffic. When you go to traffic the speed suddency goes low near 30-40 kbps. 30-40 kbps in 4G is very laughable.
As now other netoworks are also giving plan in same prise as jio. And also do not have problem of traffic. It is not good to prefer Jio.
