1. A computer system designed to communicate with a remote wireless communication device (WCD), the computer system comprising: one or more memories that store computer program code; and one or more processors that execute the computer program code, the computer program code comprising: instructions to receive sensed data from the WCD that derives the sensed data with one or more sensors associated with the WCD; instructions to make a comparison of the sensed data with reference data; instructions to communicate a message to the WCD indicating whether or not the sensed data involves an activity relating to at least one of a user need for assistance, an accident, and a crime, based upon the comparison; instructions to, when the sensed data involves the activity, enable one or more additional sensors associated with the WCD; and instructions to receive additional sensed data from the WCD that derives the additional sensed data from the one or more additional sensors.
