I am using reliance JIO sim 2 years and it is providing the best service as compare to other networks. Its 4G speed is very good and the plans it provides to a user are also reasonable and affordable. As I travel a lot and using this sim card I find my location and call anybody at any time. And the best thing about this network is that it provides the best plans that 399 rupees for 3 months with unlimited calls, SMS & internet.
