Tethering
This option allows you to share your phone’s mobile data
connection via a direct USB connection between your phone and
computer. A wireless version of this same functionality would be
the Mobile AP feature.
Note: You can not mount your phone’s microSD card to your computer while
using the USB tethering feature. If additional software or USB drivers
are required, navigate to:

Mobile AP
This feature allows you to turn your phone into a Wi-Fi hotspot.
The feature works best when used in conjunction with HSPA+
(4G) data services (although 3G service can also be used).
Important!: The Mobile AP service can not be active at the same time as
Wi-Fi. Please close your Wi-Fi connection prior to launching the
Mobile AP service.
For more information, refer to “Mobile AP” on page 174.
