For some days I have used jio-fi at home, the biggest problem I found is that its battery backup, it is a good hot spots to use the home. but if you mostly travel outside and Jio -Fi, its battery backup may make you a little nervous, because its battery backup is not something special.
And if you talk about jio-fis internet speed compared to any 4g handset, jio-fi case In Slightly slow. Jio-Fi is fine on its own price, but its battery backup is not something special. Its model and design is quite thick, due to which it looks a bit odd at putting it in pocket. And if I talk about my personal experience then its network strenth is not something special. If its design was slim and shorter, and its battery backup and network power would be slightly better then it could be a batter option for Pocket Internet.
