Reliance jio is the best network till now I used.
Reliance jio has a great offer for Samsung user that is 3-month unlimited data, voice calling, etc. The performance of the network is great. And the speed of net is awesome its super fast.
Overall reliance jio is really good, service is also good. You can surely go for it, but before taking please be sure that you have a reliance jio network available in your location.
