I am using Reliance JIO for last 4 months when I bought a new 4G smartphone.
I am a Jio Prime member.
When I purchased this SIM, there was a doubt in my mind that will it work properly or not. Because in my area there is not even a 3G circle of any other network operators like Airtel, Idea, Vodafone, and BSNL.
But the experience of using Jio is really very good.
Its cheapest data plans with high speed 4G, its Dhan Dhana Dhan offer with unlimited calls and SMS is like a revolutionary change in telecom sector of India.
According to me and my friends Jio is presentely the best 4G network.
