I am using reliance jio sim from last two months regulerly. Reliance jio provide lots of data in zero charges or we can say free. Reliance jio network quality is not very good lots of area Reliance jio network not catch. Net speed is very good. Youtube videos or live tv directly see without buffering. In my view Reliance jio need lots of work to improve their signal and network coverage area. Reliance jio voice quality is also good. Actually voice and net both quality is good but signal problem is so much.
