I have been using vodafone since last 6 year. vodafone gives me hardly 2G network in my village. But reliance jio gives me 4G network within 2 month in my village where maximum speed is 1Mbps in village areas. Voice clearity in VoLTE devices ( iphone 6s) is good. Network strength is constant. And reliance jio make a historic move against price of internet. Now we all reliase that we were robbed by all mobile network companies. Thanks Jio!
