218 3B. Web and Data Services

䢇 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):

䢇 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:

䢇 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.
