Yesterday, cellphones across the county blared out the familiar Emergency Alert System tones, normally heard on your radio or television. In June, 2012, the National Weather Service, FEMA and the FCC partnered with cellphone carriers to provide Wireless Emergency Alerts, direct to your mobile device. Now, no matter where you are, you can be notified of an emergency.
The service comes standard on new phones and operting system updates, and has limited customizable features available.
If you're in iPhone user, tap the Settings icon, then the Notifications tab.
Android users, open the Emergency Alerts app and go to the Settings menu.
Alerts issued by the President can not be disabled, but you can decide whether or not to be notified of weather emergencies or Amber alerts. For iOS users, it is either "on" or "off". Andoid users can choose whether or not to receive the alerts and whether or not they are accompanied by those jarring alert tones.
