When disaster strikes, it’s helpful to know what’s going on. This is why the UK government has launched an emergency alerts service, to be used in life-threatening situations including flooding and wildfires.
The time has now come to test how the system works – which is why every mobile phone in the UK will get an emergency alert on Sunday, 23 April at 3pm. The message, which will appear alongside a loud alarm and vibration on millions of phones, will let the government see how this new public warning system operates. Your phone will vibrate and make a loud siren-like sound for about ten seconds – even if it’s on silent.
