The jio is the best available data service in india because it is free. But apart from that I am not saticfied with its call quality it has the poor call quality I still afraid to make my jio number as a primary number. Data speed is not up to the mark as 4g network but without money it is more than enough. Now jio is providing 1gb data per day that dont feel enough also. I hope in near future jio will improve its services and it will provide us international standard in its data speed and in call quality
