Making an Emergency Call
Dial 911 to be connected to an emergency response center. If you are on an
active call, you must end it before calling 911.
active call, you must end it before calling 911.
When you make an emergency 911 call, your phone’s GPS feature begins to
seek information to calculate your approximate location. It will take your
phone’s GPS feature some time to determine your approximate location.
Even where your phone has good access to sufficient GPS satellite signals and
network assist data, it may take 30 seconds or more to determine the
approximate location. This time will increase where there is reduced access to
satellite signals. When your approximate location is determined, it is made
available to the appropriate emergency response center.

In some cases, your local 911 emergency response center may not be
equipped to receive GPS location information. For this reason, and because
the GPS location information reported is only approximate or may not be
available in your location (see “IMPORTANT: Things to Keep in Mind” on
page 120), always report your location to the 911 operator you speak to when
making an emergency call, if able, just as you would when using a phone
without GPS capabilities.

In general, if your phone has access to signals from more GPS satellites, your
location will be determined faster and more accurately than if your phone has
access to signals from fewer GPS satellites.

If your phone does not have adequate access to GPS satellites signals, the
location of the nearest cell tower in contact with your phone is automatically
made available to emergency response center, if the center has the capability to
receive such information.
