The UK is set for an unprecedented nationwide test of its new emergency alert system, but ministers are issuing urgent warnings that the loud siren-like message could have dangerous and unintended consequences.
Scheduled for Sunday, April 23rd at 3pm, every compatible mobile phone across the country will simultaneously blare a loud alarm and vibrate for ten seconds, even if set to silent. The government intends to use this system for future life-threatening emergencies like severe flooding or wildfires.
Critical Safety Warning for Drivers
The most significant warning is directed at motorists. Officials fear that drivers startled by the sudden alarm could become distracted and cause accidents. The government's official advice is clear: if you are driving when the alert sounds, you must not pick up your phone to look at or turn off the message.
Transport Secretary Mark Harper emphasised the importance of road safety, stating it is already illegal to hold a phone while driving. The alert will appear on the screen without the need to touch the device.
Covert Phones for Domestic Abuse Victims
Charities have raised a second major concern regarding victims of domestic abuse who may have secret or secondary phones hidden from their perpetrators. The alert could reveal the location of these hidden devices, putting individuals at extreme risk.
The government advises those with concealed phones to turn them off completely before the test time. Support services are urging people to share this information through safe channels to protect vulnerable individuals.
How the System Works
The alert is a broadcast from cell towers to all 4G and 5G devices within range. It does not require your phone number or collect any personal data. You can opt out by searching your device settings for 'emergency alerts' and turning them off. However, the government strongly recommends keeping them active for future genuine emergencies.
This test is a pivotal moment for the UK's national security infrastructure, but public awareness of these potential risks is essential for ensuring everyone's safety during the trial.
