I am using reliance jio from 6 months. when jio is launch.
we paid 4g data very castly. now every its free just because of jio.
relaince jio network coverage is best as compaire to other telicome network.
but customer survice is very poor. customer service take a lots of time.
jio net is super fast. no any problem in using in net service. but calling sevice is very bad many time call in not connected. I have no idea about charge ang billing because jio all service is free till 31 dec 2016.
over all im very happy using of RELIANCE JIO.
