Public warning systems
About public warning systems
Public warning systems are used to send alert messages to users with enabled mobile devices. Public warning messages
are text messages that alert users of possible threats to public safety in their area. Messages may include severe weather
warnings, missing child alerts, or other national emergencies.
Depending on your wireless service provider, public warning messages don't contribute to data usage in your wireless
service plan. Depending on your region, wireless service provider, and wireless network, this feature might not be
supported. For more information, contact your wireless service provider or administrator.
