This device is designed to receive wireless emergency alerts using the Cellular Broadcasting Service as specified in IFT-011 Pt3. If your cellular network provider supports this service, alerts will be provided while in the provider's coverage area. If you travel outside your provider's coverage area, the alerts may not be available. For more information, please contact your network provider. Wireless Emergency Alert settings are available in the Messages App settings by selecting Advanced. Once displaying alerts, the settings can be viewed and changed. This allows non-mandatory alerts to be deselected and for test alerts to be enabled if required. An option to enable text-to-speech also exists, allowing the text alerts messages to be spoken aloud for the user to hear the message.
