Making Emergency Phone
Calls
Your phone supports emergency calling.
Emergency phone calls can be made even when
your SIM is blocked or not in your phone.
Dial 911 to be connected to an emergency response
center. If you are on an active call, you must end it
before calling 911.
When you make an emergency call, your phone’s
GPS Enabled feature can help emergency service
personnel find you, if you are in a location where
your phone's GPS antenna has established a clear
view of the open sky and your local emergency
response center has the equipment to process
location information. See “GPS Enabled” on page
67, and particularly “IMPORTANT: Things to Keep
in Mind” on page 67 and “Making an Emergency
Call” on page 68, for more information on the
limitations of this feature. Because of the limitations
of this feature, always provide your best knowledge
of your location to the emergency response center
when you make a emergency call.
Important: Emergency calls cannot be placed while
the keypad is locked.
Important: If you have not registered on the
network, emergency calls cannot be
placed while your SIM is in your phone.
Important: If you are bringing your phone number to
Boost Mobile from your previous carrier,
the 911 emergency response center will
not be able to make a callback to your
temporary Boost Mobile phone number
after the phone number you requested
has been activated on your Boost Mobile
phone.
