I start using reliance jio sim card from 7 september after the welcome offer starts.I get it from my nearby reliance digital store with my Asus Zenfone max.Firstly when I try to televerify this sim card it shows a error and for one whole day it nit verified at all.Then I tried again to televerify and after 3 days I got televerified and I start using it.I used approxmately 3 Gb first day and the experiance is OK.It shows the speed of 4Mbps.So thats enough for a free 4G internet.I try to use calling service of Jio but I am not able to make calls because my phone is not VoLte supported but I an happy with Its data service.So thats all about my experiance.
