I bought this Wi-Fi device 5 months ago.
This is an Osm product given by Jio.
It connected up-to Max 31 devices at a time, thats just incredible.
Just only inserting a sim of Jio we can connect up-to 31 devices.
It is small in size very easy to carry.
Having a non touch screen, good for seeing data signal Wi-Fi signal, and battery indicator.
Now about battery life that’s just Osm giving about 6-7 hours on a single charge.
Overall best device for 3g phones and people who want Wi-Fi
