I was use jio network from one year. At first jio give free service to his costomer. In starting costomers face many problem like call drop, call fail to connect to network. Then its getting in better condition.
Before 6 month I was recharge my mobile no with RS 309 in offer jio dhan dhana dhan offer. I will use jio service in super condition some time it get very slow net speed but the speed is sufficient in suffering on net.
When I was recharge with rs 399 I was use 2 month in better condithion but when it get in last month jio is not give me net speed in this month most of time was suffering from low speed and a poor network problem so I am very disappointed from this service.
Jio give a good network to his new costomer and a better network than old costomer.
I will tell that from my experience.
