Unlimited phone plans are ONLY unlimited for PHONE data use. Unlimited phone plans only allow 5-15GB of tethering. (the ability to use the phones data with your computer, tablet, or other connected devices.) That is the equivalent of streaming 2-3 HD movies. Unlike an unlimited phone plan, our plans and devices can entirely replace your slow home or office internet solution for an unlimited, unthrottled, high-speed wireless data connection.
