Jio is a revolution in Indian telecom network.i used many networks but I have never seen this type of network.its 4g speed is excellent.and voice clarity is good.i love jio offers too.compared to other network the speed of dialing is very fast.but the main disadvantage is the data speed is very less in some areas.there is a call drops on busy hours.if we want to do urgent call it is difficult.how ever it is good, hope it is first step for digital India.it will be quit useful for the students like me .
