What to know about Wireless Emergency Alerts

We send Wireless Emergency Alerts (WEAs) on behalf of federal, state, or local emergency management agencies. These are free notifications that have a special tone and vibration. 

Notice about the transmission of WEAs sent through the Commercial Mobile Alert System
AT&T Mobility offers wireless emergency alerts, including enhanced geo-targeting, within parts of its service area, as defined by the terms and conditions of its service agreement, on WEA–capable devices. There is no extra cost for wireless emergency alerts.

Wireless emergency alerts, including enhanced geo-targeting, may not be available on all devices or in the entire service area, or if you’re outside of the AT&T Mobility service area. For more info about this service and WEA–capable devices, please ask a sales rep, or go to

Notice required by FCC Rule 47 CFR 10.240 (Commercial Mobile Alert System).

Each WEA broadcasts at a set volume that can’t be changed. These alerts don’t interrupt phone calls, sending emails, or other online transactions. But they may override any blocks you have on your phone, like do not disturb.

If you get a WEA, take any recommended action and check your local media or the National Weather Service for more details.

Alert types
There are four types of Wireless Emergency Alerts.
  • Imminent threat alerts warn of severe weather or other disasters that pose a threat to life or property.
  • Public safety messages prescribe one or more actions likely to save lives or safeguard property. They’re related to imminent threats.
  • AMBER alerts notify communities about missing children.
  • Presidential alerts are issued by the U.S. President. You can't opt out of this type of alert.

These alert types may be received as an imminent threat or AMBER alert type, depending on the sending agency policy.
  • Silver alerts for missing older adults with dementia or Alzheimer’s.
  • Blue alerts to help capture violent criminals who kill or seriously wound federal, state, or local law enforcement officers.
  • Endangered missing persons alerts for someone missing with an intellectual disability.

Undelivered alerts
Expected to get a WEA but didn't? There are a few reasons for this.
  • Your phone can't get WEA alerts.
  • You opted out of imminent threat alerts or AMBER alerts.
  • You aren't in an area targeted to get an emergency alert.
  • Your phone was turned off or was in use when the alert was sent.
  • Your phone isn’t running the latest software. Learn how to update it
