STOP the KLAXON !!! Turn off amber alerts I have multiple phones I left the alerts turned on on all but one . I turned the alerts off on the phone that I am on 24 Hr. call on so if it goes off it's something that actually involves me . When I get up I can look on the other phones ... That being said here is the turn off for those that don't want an alarm at 3 am ... Those who want to manage subscriptions and either opt in or out, mobile phone owners can send the keyword "help" to the short code 26237 (AMBER). To enroll or modify, send the keyword "Amber + 5-digit zip code." To cancel send the keyword "stop."
