The first 30 minutes
- 01
Handle immediate hazards first: call 911 if available, move out of danger, and follow official evacuation or shelter instructions.
- 02
Read any Wireless Emergency Alert completely and capture the key action, area, and expiration before dismissing it.
- 03
Send one concise SMS to the household relay contact with your location, condition, next action, and next check-in window.
- 04
Stop automatic photo backups, streaming, hotspot use, and unnecessary apps; lower screen brightness and use low-power mode.
- 05
Switch to a battery-powered NOAA or AM/FM receiver for continuing information instead of refreshing social feeds.
- 06
If no message is acknowledged by the agreed deadline, move to the alternate method or safe meeting protocol.
Match the symptom to the next action
| Symptom | Likely constraint | Useful action | Avoid |
|---|---|---|---|
| Calls fail; SMS may work | Congestion or call-routing trouble | Send one short text and wait for the plan’s retry window | Repeated redialing and group-call loops |
| Phone shows no service | Coverage, tower, or device issue | Preserve battery; check a safe nearby location only if movement is already necessary | Driving around solely to hunt for signal |
| Data fails; voice works | Data-network congestion | Use a brief voice call only for an essential decision | Video calls and large attachments |
| Everything is offline | Local infrastructure or power failure | Use radio information and the written meeting/check-in plan | Assuming an unverified social post is official |
Keep the phone useful for longer
Airplane-mode intervals
If there is clearly no service, use scheduled connection checks rather than leaving the phone searching continuously. Keep emergency alerts and local instructions in mind before disconnecting.
Paper replaces screen time
Use printed contacts, maps, medication details, and meeting points so the phone battery is reserved for communication.
Local broadcast matters
NOAA Weather Radio and local AM/FM stations may provide information even when internet access is unavailable.
Verify before sharing
Forward only information tied to an official source, a clear timestamp, and a defined affected area.
Cellular and alert references
Rules, plans, subscriptions, and specifications change. Follow current official instructions and the exact model manual.
Cell-outage FAQ
Are Wireless Emergency Alerts ordinary text messages?
No. They are geographically targeted one-way alerts delivered through a dedicated system. They do not provide a reply channel.
Should I turn my phone completely off?
That depends on the hazard and plan. A scheduled low-power check can conserve energy, but turning the phone off also prevents alerts and incoming messages during that period.
Can Wi-Fi calling work when cell towers are down?
It may work if the internet connection, router, account, and power remain operational. Treat it as an alternate path, not an independent emergency system.
