Your E-911 address is used by emergency services to determine your location. When you enable WiFi Calling, you'll be asked to register a physical address in order to ensure that you’re provided with emergency services if you call 911 over WiFi. It is important to keep this registered address updated with your current location. 911 calls will first attempt to use the cellular network. If you are at your registered location and wireless coverage is not available, your phone will try to complete a 911 call using WiFi Calling functionality. If your GPS location is available, the phone’s location may be transmitted to the PSAP, but if GPS or your phone location is not known to the network, your registered location will be used to route the call. Therefore, it is very important to keep your registered location up to date.
You can update your E-911 address on your phone or you can do it in your account on My Altice.
911 calls may not be available or may be limited when using WiFi Calling for a variety of reasons, including but not limited to, network and/or internet connectivity or congestion, loss of commercial power, interference, and/or equipment or device failure and other problems.
