Warning apps and EU-Alert

How public warnings reach you in Europe: official warning apps, cell broadcast (EU-Alert) and what to enable on your phone before a crisis.

When a flood, storm, chemical release or other danger is imminent, seconds matter. Europe uses two complementary channels: national warning apps (and websites) and cell-broadcast messages (often branded EU-Alert or a country name like NL-Alert). You should turn both on where available — apps need data and opt-in; cell broadcast can reach most modern phones in a cell tower area without an app.

Cell broadcast / EU-Alert

These are special network messages, not SMS from a contact. They can sound a loud alarm even in silent mode on many phones. Enable “emergency / government alerts” or “EU-Alert” in system settings (wording varies by Android/iOS and country). You do not install an app for the basic broadcast. Keep software updated so alert channels stay supported.

National warning apps

Apps such as NINA (Germany), or your country’s official equivalent, add maps, multi-hazard detail and history. Install only from official stores or government sites. Allow notifications. They complement — not replace — cell broadcast and local sirens or radio.

Good habits

Test that notifications work. Know what local sirens mean in your municipality. Keep a battery or crank radio as backup when mobile networks fail. In any life-threatening emergency call 112 free, without credit, on any available network — do not rely on SIM-less calling in every country.

App availability and settings differ by country and phone. Prefer official government sources; crisisplan is not affiliated with them.
