Learn how to use the emergency alerts messages on your Samsung Galaxy S4. The Samsung Galaxy S4 is designed to receive wireless emergency alerts from the Commercial Mobile Alerting System (CMAS) which may also be known as the Personal Localized Alerting Network (PLAN). If your wireless provider has chosen to participate in CMAS/PLAN, alerts are available while in the provider’s coverage area. If you travel outside your provider’s coverage area, wireless emergency alerts may not be available. For more information, please contact your wireless provider.
Emergency Alerts allows customers to receive geographically-targeted messages. Alert messages are provided by the US Department of Homeland Security and will alert customers of imminent threats to their safety within their area. There is no charge for receiving an Emergency Alert message.
There are three types of Emergency Alerts:
Alerts issued by the President
Alerts involving imminent threats to safety of life (Extreme and Severe)
AMBER Alerts (missing child alert)
Customers may choose not to receive Imminent Threats (Extreme and Severe) and AMBER Alerts. Alerts issued by the President cannot be disabled. To disable Imminent Threats and AMBER Alerts, follow the instructions below:
From the main Home screen, tap Messaging icon.
Press Menu key > Settings.
Scroll to the bottom and tap Emergency alerts.
All alerts are enabled by default (checkmark showing). Tap on an alert option to disable the alert and remove the checkmark.
