The jiofi dongle is very good, very mobile, can keep it in your pocket and go. But the thing I hate the most is that it gets way too heated. And it gets a lot of scratches too soon. To be precise I’m talking about the wifi dongle and not the network which is amazingly speed and stable except at a few places. And coming back to the device, the heating issue has caused my dongle to malfunction. It’s been almost 8months since I bought this.
