Reliance jio is a biggest company, it provides 4G services. So I want to opt this service. At a releasing time it’s service is so fast and quick work. But now this day it’s service is not running better. Data speed become slow and calling not work properly. So I am worried using this service. It gives own service on some mobile handset, no special selling only sim. So it’s user is not more than to other network. If he sell only sim then its customers will become more to take this 4G service at the low cost rate.I have no any billing issues.
