Jio is providing best network coverage, even in the rural and hilly areas. Internet Speed is very much fine. I am using it from September 2016. Getting on and avg speed more than 10 mbps in mumbai. Xustomer service is also very good. They listen first and try to solve the problem. Other operators even dont listen the problem. Till now its free service. but from 1st April, they are going to charge. But the money you will pay for the service is very much less.(303 per month) Keep Joining in Jio prime
