I am using JIO its from 6 month. The overall My experiences is good with JIO service. like Voice calling, DATA, videos calls. The Internet 4G speed are really great. Better than even my BSNL broadband. I am getting a download speed upto 10 Mbps mad upload 5 to 7 Mbps. Call quality is not better but it is good. and after all, dude its totally free. SMS getting delivery quickly.Just like any other network. So, I am enjoying JIO service continues.
