When is my data connection active?
Your connection is active when data is being transferred. Both
incoming and outgoing calls are allowed. When active, the or
indicator animates on your phone's display screen.
When is my data connection dormant?
If your phone receives no data for 10 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 no data is received 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 phone; however, you will
not be able to browse the Web or use other data services. 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/Tools > Settings > Others >
Data > Data On in your phone's menu.
