Mobile HotSpot

The Mobile HotSpot feature lets you share your mobile device’s data connection with other devices by turning your device into a wireless access point. You can connect up to 10 wireless devices via Wi-Fi®.

WARNING: Using your mobile device as a mobile access point is data-intensive and will dramatically reduce battery life. It is recommended you contact your wireless carrier and ask about availability with your plan. It is also recommended you keep the device plugged in while the HotSpot feature is turned on.
