Jio Phone service is not upto mark, From the launch of Jio I always hear that Jio is very good service, free calls, free data, free sms. So last month I decided to quit Idea and port my number to JIO, but again I found problem in Reliance JIO service, maximum times when I call someone, I am not able to hear voice from other side, I have to disconnect the call and need to call again. Next time call is connected and running well but sudden again found same problem in JIO service. Regarding 4G data speed that is also not upto the mark. I am completely disappointed with JIO 4G service.
