When is my data connection dormant?
If your device receives no data for 10 seconds, the
connection goes dormant. You can make and receive
voice calls while data service is also active. (The
connection may become active again quickly.) If your
phone receives no data for an extended period of time,
the connection will terminate. While the phone is using
a DUN (Dial-up Network Profile) Bluetooth data service,
you will be unable to receive an incoming call.
Can I sign out of all data services?
No. Although you can not sign out of all data services,
you can sign out from Web Browser access without
turning off your device. While signed out, you can still p
lace or receive phone calls, check voicemail, and use
other voice services. You may sign in again at any time.
To sign out, press and touch Main > Settings >
in your
Parental Controls > Restriction > Web Browser > Off
device's menu.
