First I would like to say jio heads off to u. Because in small time u show a big achievement which non one can show u create your own empire in a telecom connection. So as its a jio dongle device which is good in looks as well as well as connectivity. In this device we can join 31 device in one at a time but I can say only that plzz only connect 2 to 3 device coz its does not provide sufficient speed when large no. Of device connected. And I whould only say tha its a great device or a opportunity to those people who does’t have a 4g phone for this device we can also enjoy for internet as well as voice calling in 2g as well as 3g phone. As its service and support is also good.
