This is the best ever entry of a network.The preview offer of Jio contains unlimited data and calls .What else do we need other than such an amazing offer?.talking about the network coverage it is quite good as well.But it is not yet reached completely to some of the rural areas .The speed they are providing is mind blowing.In my place I got the best ever speed of 25 mbps .But am not that impressed about the calls.Sometimes the call wont be get connected even though i’m okay with because all I needed is data.The call clarity was exceptional when I had full network coverage.The sim activation was bit worse because it took almost a week to activate for me.Hope the review will help you guys.
