Tethering (hotspotting) occurs when you allow other devices, such as a computer or tablet, to use your phone’s data to connect to the Internet. Tethering can be achieved by connecting your secondary device to your phone via USB cable, or by turning your phone’s Wifi on, and connecting your secondary device to that network.
US Mobile allows you to tether your phone to provide internet access to other devices.
