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 safety in their area. Messages may include severe weather warnings, missing child alerts, or national emergencies.
Depending on your wireless service provider, public warning messages don't contribute to data usage in your wireless service plan. This feature might not be supported, depending on your region, service provider, and wireless network. For more information, contact your service provider or administrator.
You might not be able to unsubscribe from some public warning messages, depending on your region and wireless network.
