Cell phones are an important public safety tool, but they also create challenges for public safety and emergency responders. Since 9-1-1 calls made on cell phones may not automatically provide the 9-1-1 operator your phone number and approximate location, be ready to provide this critical information.
If you are in an area where your cell phone is searching or scanning for a signal, or there is no signal, your 9-1-1 call may not go through. If this happens, either move for a better signal or find the nearest telephone and call for help.
It is important for cell phone users calling 9-1-1 to remember some basic ABCs:
* Always be AWARE of your surroundings. Tell the 9-1-1 operator the location of the emergency. Provide landmarks such as cross streets and mileposts.
* BE PREPARED. Memorize the cell phone number so it can be readily given to the 9-1-1 operator when asked.
* Stay CONNECTED. Do not hang up until told to do so. If you should get disconnected, call the 9-1-1 operator back.
