If certain features are in use, you may first need to turn those features off before
you can make an emergency call. Consult this guide or your service provider. When
making an emergency call, give all the necessary information as accurately as
possible. 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.
