Hii frnds I have been using reliance jio from 6 months ago. at the first time its speed is mind blowing.after the prime membership I got its problem any time. when I am at home ithas got emmergency calls only and net speed is very low as 2g.when I call to its customer service then they says that the network is good at our area but not is true.about its charges and biling is good for all time. I only take it for its data speed now its gone. so I want to change my sim.
