TETHERING & WI-FI SHARING
To use tethering or Wi-Fi sharing, you must
have a Tethering and Wi-Fi Sharing service
plan.
Tethering
Your phone has the capability to share
its mobile data connection with a single
computer via a USB cable.
n
Tethering works with Windows®
7, Windows XP, Windows Vista®,
and Linux. For more information on
tethering with operating systems, go
to www.android.com/tether#usb.

For Windows XP, first install the
driver on your computer before you
can tether. To install the driver, go

When you connect your phone to
your computer with the USB cable,
you can either tether or access files
on the memory card but you cannot
do both. If you want to use your
computer to access the memory card,
then you must not turn on tethering.
Wi-Fi Sharing
You can share the mobile data connection
from your phone with other devices by
turning your phone into a portable Wi-Fi
hotspot.

When your phone is serving as a
Wi-Fi hotspot, you cannot access
the Internet via its Wi-Fi connection.
