Provided you can get a signal from a cell tower, 911 service will always be available on your mobile phone. When you dial 9-1-1 from your Execulink Mobility device, you will be routed to the PSAP (Public Service Answering Point) closest to this tower.
Enhanced 9-1-1 (E 9-1-1):
Phase One Areas
The PSAP receives your mobile phone number, area code, and the location of the cell tower handling your call.
Phase Two Areas
The PSAP’s connection to a Phase Two-ready mobile device receives your area code and phone number but also your longitude and latitude. Geolocation is especially useful if you are unable to give the 9-1-1 operator your exact location due to illness or injury.
