I have been using jiofi foe last 8 months it is too good compare to other routers which need to be used in computers where jiofi is portable which can be use any one and connect upto 20 members if you have high speed data in your area, coming to specification it has dedicates micro sim slot in jiofi and a micro sd card reader, the package come with device and a charger and battery backup not that good it need more improvement in battery section otherwise device is awesome with high speed wifi thanks jio.
