Portable jiofi hotspot
I will talk about jiofi 3 only
It is good than last versions
I am also using it
2300 mah battery
Wps button
Up to 31 devices can connect
You can insert sd card also
And can share data really very fast
You can make free voice calls using
3g phone also
Nice speed
More than the speed you will get in normal 4g mobile phones
You can use it without battery also
You sholud connect charger
Best trick ( hack ) is that
If u don’t have nice signals inside your room
You can keep hotspot outside and can experiance amazing speed
Good battery backup
