Emergency #
The Emergency # option lets you enter and store up to three
emergency numbers in your phone. Each number can be up to 32
digits long. You can dial your emergency numbers any time, even
when your phone is locked or restricted.
Remember to always turn your phone on and check for adequate
signal strength before placing an emergency call.
Note: Emergency number 911 is hard-coded into your phone. You can dial this
number any time, even when the phone is locked or restricted. If you call
911 you hear an audible tone and an Emergency prompt appears in the
display for the duration of the call.
Important!: Because of various transmission methods, network parameters, and
user settings necessary to complete a call from your wireless phone,
a connection cannot always be guaranteed. Therefore, emergency
calling may not be available on all wireless networks at all times.
DO NOT depend on this phone as a primary method of calling 911 or
for any other essential or emergency communications.
