I am using JIO’s network from 2 months. I am fully satisfied with my JIO 4G sim. if I talk about the speed of jio it is fantastic. Speed of my jio 4G network is very fast, it gives me every time 2-3MBPS speed. Best thing of JIO is it provides me a free calling for a life time and jio gives me 1 GB free data daily under their HAPPY NEW YEAR OFFER. best thing of this company is if jio launched the plan of 4G they will very very cheaper then other company’s 4G plans so JIO is best company for me.:)
