218 3B. Web and Data Services
ⅷ If you are on a voice call, you will not be able to
establish a 3G data connection.
With DDTM on (configured in
Call settings):
ⅷ You cannot use voice and data services
simultaneously. If you receive a call while data
service is active, your device will forward the call to
voicemail. You can place an outgoing call at any
time, but it will interrupt any in-progress data session.
Your device will not automatically resume an
interrupted data session.
With DDTM off or on:
ⅷ You can make or receive a voice call while you are
connected to the 4G data network. Incoming calls
will not disrupt or suspend your data connection.
When is my data connection active?
Your connection is active when data is being
transferred. Outgoing calls are allowed; incoming calls
go directly to voicemail. When active, the or
indicator animates on your device’s display screen.
When is my data connection dormant?
If your device receives no data for ten seconds, the
connection goes dormant. When the connection is
dormant, you can make and receive voice calls. (The
connection may become active again quickly.) If your
device receives no data for an extended period of time,
the connection will terminate.
Can I sign out of data services?
You can sign out without turning off your device;
however, you will not be able to browse the Web or use
other data services (unless you establish a Wi-Fi
connection.) While signed out, you can still place or
receive phone calls, check voicemail, and use other
voice services. You may sign in again at any time. To
sign out, go to
Settings > Wireless & networks and clear
the
Mobile network check box.
