Unlimited plans offered by the carriers are ONLY unlimited for PHONE data use. Unlimited phone plans can allow only 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 a couple of HD Netflix 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.
