I bought jiofi 4g router for my 3g handset. Because Jio sim was not available for 3g handset. I was really happy to buy it. But after use it I was upset. I know that this router never give me 4G speed in 3g handset. But the speed giving through this router lower than 3G. Very bad network. When I travell by train, this router do catch only 1 to 2 network. For this some time I sufferd. This is good product for carry easily, its also run for 8 to 10 hours, but if this router not work for which I bought it then why I use it?
