Jio wifi is really a good portable wifi you can easily port anywhere and if you are a traveler then this is the good wifi for you
signal strength - signal strength of this wifi is really a very good sometimes a some problem is came for connecting but after some time they resolve without any thing doing in this
material quality - nice quality sometimes I dorpped on the floor but the material is very good and reliable.
I like this device personally because it does not feel like a wifi router at the time of carry we can easily carry this anywhere it feels in a pocket like a mobile.
