Hello guys today I am good to tell you about the jio4g voice application. I am using this application form last 7 months. This is worst app ever it calling quality is very bad you can hear anything clearly and the tone of the person who is speaking is also changes. The application is for use the free calling service of Jio sim and form now you should not install this app because the Jio calling system is stop you can only send message from this app think so. Form now onwards installing this app is just waste of time
