NO matter reliance jio is faster a lot more than idea/vodafone/airtel 4g, But not as of now! I personally compared idea 4g vs jio 4g when it was just launched in beta. Lets see the impression after free offer ends. Currently as of january 2017 , its speed have improved by reducing limit to 1Gb, currently on an average user gets speed of 300-400kbps ( 3g)
