JioFi is a very nice wifi portable device. U can carry it anywhere and connect 6 persons to this wifi device for best speed. As the customers are increasing jio net speed is going very slow. initially it provides 10mbps downloading speed but now it provides 1mbps downloading speed. Jio must work on it to imrove and maintain net speed. Bit jio will create tuff comptition to other service providers. So be ready.
