Tethering and Portable Hotspot
Portable Wi-Fi hotspot
Turning ON Portable Wi-Fi hotspot turns your phone into a
Wi-Fi Internet access point (hotspot) and allows up to 5 other
devices to connect to it using a Wi-Fi connection. These
devices have Internet access through your Wireless
Provider's data network.
To enhance security, you can create an allowed device list
and set the connection mode for Allowed devices only.
This feature enables mobile data and consumes more battery
power.
Note: Using this device as a Hotspot requires a subscription to
data service. For more information, contact your
Wireless Provider.
