Im using jio sim from last one month.about my experience jio was third class service.no coverage in my area as well as my home. After collecting my jio sim I had no problem with oprating no coverage issue no buffering but after 15-18 days there are many problem with me using the jio sim. Jio sims speed is very slow when I am downloading somethig it has speed about 80 kbps to 120 kbps.this is 4g or 2g network.therefore I wroted the title which are aas dikhakar ghas khilana
