Hey guys, I have been using Reliance Jio since August 2016 and I got a bitter experience with it. Although it provides low cost 4g services but the signal strength isn’t stable. Sometimes the downloading speed reduces upto a level slower than even the 2g network. But the voice calling service is good. If your phone doesn’t support volte than you have to download ’jio 4g voice ’ app from the Google play store. If your phone support volte than no need of the app.
