I am feeling proud that I am a JIO user.JIO network almost covers the entire India.They are providing a free service, unlimited calls, unlimited messages, unlimited data.Really made life easier.They are providing customer service in your regional language.The average 4G data speed is 50mb/sec, it is really amazing and all what I have told is totally free of COST.Really I am satisfied with the customer service.The prepaid charge is zero rupees till march 31st.After that they are going to provide cheapest service here before.
