I use jio sim since 1year.at starting it was giving a very nice services with variable benefits.that time the network service and internet speed was really good.but nowadays jio gives really very bad service.the internet of the sim becomes useless now.i cant do anything.no message no phone call nothing.their also have a sound problem.though it is a 4g sim but the internet speed is like 2g.use of jio sim is very irtitating now.
According to me they should improve their service capability.
