I have brought the jiofi 3 months ago and it give me wrost feeling because the internet connection of this hotspot or router is sometimes or you can say all time doesn’t give the 4G experience ! The connection is active all time but net speed is very slow which is not 4G ! This device is good but the custumer service of jio is also wrost ! Service and support are not good you can say that it is bad ! I only liked this device’s small size and we can handle it all time in our pocket ! Because of this reason I am giving this device only 2 star ! I recommend you to donot buy this device beacuse if you get a faulty piece then you will not get the custumer support which you must get !
