• About emergency callback mode
About A-GPS support
Depending on your handheld version or service
provider, your handheld might be enabled with
Assisted Global Positioning System (A-GPS)
support.
If your handheld is enabled with A-GPS support,
when you make an emergency call from your
handheld, or during Emergency Callback Mode, an
emergency operator can estimate your
approximate location (subject to A-GPS
limitations). In the handheld options, click
Location Based Services, and set GPS Services to
911 Only/Location Off.
To allow an operator to estimate to your
approximate location at other times (subject to A-
GPS limitations) set GPS Services to Location On.
Warning:
In an emergency, always provide detailed
information about your location to the emergency
operator. Because of certain limitations in A-GPS
technology and emergency infrastructure, the
emergency operator might not be able to estimate
your location using only A-GPS information.

About emergency callback mode
When you end an emergency call, the handheld
enters emergency callback mode. Emergency
callback mode is active for five minutes and
enables the operator to call you back or determine
your approximate location.
In emergency callback mode, you cannot send and
receive messages or browse web pages. If you
make a call to a non-emergency number during
the five-minute period, emergency callback mode
is disabled.
