Emergency Alert Configuration
This device 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
• AMBER Alerts (missing child alert)
Customers may choose not to receive Extreme Alerts, Severe Alerts,
and AMBER Alerts.
Important! Alerts issued by the President can not be disabled.
To disable Extreme, Severe, and AMBER Alerts:
1. From the Home screen, tap
2. Press
3. Scroll to the bottom and select Emergency alerts. All alerts are
enabled by default (checkmark showing).
