Preguntas frecuentes sobre el cumplimiento de E911
¿Qué es el servicio móvil Enhanced 911?
Our mobile network routes 911 calls to designated emergency call takers, often local or county police, fire and rescue departments, known as Public Safety Answering Points or PSAPs. We also provide PSAPs with what's known as Enhanced 911 or E911 service where PSAPs have upgraded their equipment. E911 automatically provides call takers with the mobile phone number, cell site and sector, and the estimated latitude and longitude location of the 911 caller if the PSAP is capable of receiving it.
In select areas within our coverage area, you can also send a Verizon text message to 911, but you're encouraged to make a voice call if able.
What happens when I call 911 using my mobile phone?
Las llamadas al 911 se dirigen y responden de acuerdo con las pautas establecidas por los funcionarios de seguridad pública de tu área. For example, some Public Safety Answering Points (PSAPs) answer emergency calls centrally for their entire state, others for their county or town. Most transfer calls or dispatch a responder nearest to the emergency. 911 calls should only be used for true emergencies, and prank 911 calls using our service may result in service termination.
We provide enhanced location information to emergency call takers but can't guarantee your precise location. Los teléfonos móviles se ven afectados por el entorno. Factores como el clima, el terreno y los edificios de los alrededores pueden afectar el servicio y la capacidad de calcular la ubicación de la persona que llama, en particular para llamadas al 911 realizadas en interiores. In some places emergency call takers still rely only on the caller's descriptions to locate and dispatch help to people in emergency situations. Siempre debes decirle tu ubicación, si es posible, a quien contesta la llamada de emergencia.
Our phones are designed to remain in emergency mode for approximately 5 minutes once 911 has been called to give public safety responders a better chance to call you back if the original call becomes disconnected. Although it varies by phone model, emergency mode can generally be exited before 5 minutes are up by pressing the End button twice or simply by making a non-emergency call.
Do Not Let Your Children Play With Old Cell Phones. Because old cell phones are still able to call 9-1-1 even if they are not active with a wireless carrier, they should never be used as toys.
- If you use a third-party app you downloaded to call 911 rather than the native app included with your phone, your call may not be completed.
- If you have Usage Controls, you may need to reset them after calling 911.
- Use of certain features like call forwarding can affect a PSAP's ability to call you back if the call is disconnected.
How do I send a text message to 911 using my mobile phone?
If you're in an area that supports text messages to 911, you can send a new message addressed to "911" and enter your message. Information such as the problem and your location are important to include in your message. Also, when sending an emergency text message, don't include other recipients or attachments (i.e., photos, emoticons and videos).
- Sending a text message to 911 isn't part of the Enhanced 911 (E911) service that's available for voice 911 calls, so it won't automatically provide your location to the emergency call taker. If you send a text message to 911 in an area that doesn't support text to 911 service, you'll receive a message back indicating that your message to 911 wasn't received and a call should be made.
- If you use a third-party app you downloaded to send a text message, it may not be received.
Where is E911 available?
Our voice Enhanced 911 service works only where Public Safety Answering Points (PSAPs) have upgraded their equipment and systems to be able to read and use the Enhanced 911 location data.
If interested, you can contact the local or state elected officials or law enforcement department to find out if the PSAP serving your area has updated its systems to use the wireless Enhanced 911 information or when wireless E911 service will be available in your area. Only call 911 in case of emergency and not to find out if E911 is available in your area.
Can I make a 911 call over Wi-Fi?
Yes, your phone will first attempt the 911 call over wireless networks, but if those are not available Verizon has the capability to route emergency calls over an available Wi-Fi router. Calls will route to an emergency dispatcher, which will use the address associated with your phone number to determine your location. To ensure that your calls successfully route over Wi-Fi, you must do the following:
- Enable Wi-Fi Calling on your phone. For information on Wi-Fi Calling, including how to enable it on your phone, visit our Wi-Fi Calling at Verizon FAQs page.
- Update your correct Emergency Address (E911) in your My Verizon account. Each individual line holder on your account should enter their own address. Visit our My Verizon Website - Update Connected Device Emergency Address (E911) page for instructions. Emergency services will only dispatch to the address you have entered. If you change locations, you must update your address accordingly.
If your phone is not authorized to use the available Wi-Fi router, or if the router's broadband connection is down, Wi-Fi 911 calling will not be available.
Note: If you are using a third party application to make calls, Verizon is not responsible for how that third party app handles emergency calling.
What is a GPS-capable phone, and why is it important for Wireless Enhanced 911?
We provide E911 location technology built into our phones. Currently, our network assists GPS-capable phones to use signals from the Federal Government's Global Positioning System (GPS) satellites to help estimate your location when you make a 911 voice call. Our location technology provides the most accurate mobile wireless location capability over varied terrain and is generally capable of estimating locations within 50 to 150 meters depending on the environment in which the 911 call is placed. Location information for 911 calls placed indoors may not be as accurate in some cases, but we are working on new technologies to address that.
Mi teléfono dice GPS. ¿Qué significa? Can other people or government agencies see where I'm located?
All new phones sold since December 31, 2003 are GPS-capable, which means there's a chipset in the phone that will help provide location information to a Public Safety Answering Point (PSAP) when someone calls 911. The phone is not a stand-alone GPS device. It doesn't support or initiate any kind of individual tracking capability. The location-determining capability becomes functional only after calling 911 when the network is prompted to determine the phone's location using our network and the GPS technology.
