If certain features are in use (Keyguard, fixed dialing, restrict calls, and so
on), you might first need to turn those features off before you can make
an emergency call. Consult this guide and your local cellular service provider.
When making an emergency call, remember to give all of the necessary
information as accurately as possible. Remember that your wireless phone
may be the only means of communication at the scene of an accident—
do not end the call until given permission to do so.
