I have been using Reliance Jio as my primary phone number for more than 6 months now the experience is good or better, according to me.
The speeds are really great. Better than even my broadband. I am getting a download speed of 15+ Mbps.While downloading, the speeds vary from 5 Mbps to 1 Mbps. But after the file is downloaded half, the speed will throttle down to 600 to 900 Kbps. I should mention that the files are more than 150 Mb. But I am not getting any throttle while downloading anything from Playstore. So this is not that bad.
