Alert on your phone
Every EU country must be able to warn people by mobile phone. The message says what is happening and what to do. It is switched on by default on almost every phone.
Siren
Many countries test their sirens regularly. If you hear a siren outside a test, go inside, close windows and doors, switch off ventilation and listen to the radio.
Radio
