utilizes the instantaneous and universality of cell phones with text message capability to send out the Amber Alerts. When a child is reported missing, after initial steps are taken where there is reasonable belief a child has, in fact, been kidnapped, this system sends text messages to all opt-in wireless subscribers in that area.
