A motion sensitive communicator (40) employs an assembly of a wireless phone (41), a motion sensor (44) and a battery (45). In operation, the motion sensor (44) power couples the battery (45) to the wireless phone (41) responsive to a sensing of any movement of a portable defibrillator (20) supporting the communicator (40). A power coupling of the battery (45) to the wireless phone (41) automatically activates the wireless phone (41) to register to a wireless network, and an activation of the wireless phone (41) enables the wireless phone (41) to execute a call to an emergency service center over the wireless network responsive to a manual actuation of the wireless phone (41). The battery (45) is power decoupled from the wireless phone (41) responsive to an absence of a call from the wireless phone (41) to the emergency service center within a time period initiated by a power coupling of the battery (45) to the wireless phone (41).
