Abstract
A PC card for enabling a host device for use on a telecommunications network. The micro-processor based card includes transmission and receiver circuitry which form a wireless telephone and a telemetry receiver. The telemetry receiver is used to receive a “wake-up” telemetry signal which activates the card and causes the wireless telephone to call a predetermined telephone number. The call terminates at a telecommunications network switch which then establishes a two way connection between the host device and the person wishing to have the communication.
