A handset uses one or more systems, such as GPS, a carrier-based network or a wireless local area network, to ascertain its location. The handset can include sensors, such as temperature or heart rate sensors. In response to detecting an attempt to place an emergency call or send a message, or in response to automatically detecting an emergency, the handset provides a server with the identity and location of the handset and information about the emergency. The server provides the handset with information to correct errors in the location information or the server corrects the location errors. Communications between the server and handset are carried over the carrier-based network, WLAN and/or another wireless channel. The server displays information about the handset, a user and the sensors, so a dispatcher can dispatch assistance and/or provide information about the emergency to another agency.
