I am using this product for last two years. Two years ago the speed of this network was very good but now a days the speed is very bad like 2G. But I am happy with the call connection and its plans. The JioFi device disconnects automatically after few hours of use. The device heats after using two hours. Whenever I trying to connect it says connection failed. The speed of cable connection is very bad if you cant use the WiFi Hostspot connection. But at the end the battery backup is little bit good. I gave only two stars for its internet connection.
