The much-anticipated emergency alert test was sent to phones across the country today (April 23), but it did not land everywhere at the expected 3pm. Even though many were counting down for it, the alert still made some phone-owners 'jump out of their skin', with some social media users reporting it came through earlier than they thought.
The nationwide alert forms part of the UK government's toolkit of services to warn residents if there is a nearby danger to life.
Following a large media campaign, the government sent out a test alert to all 4G and 5G capable mobile phones to show people what a real alert would look and sound like. The loud alarm blared until it was manually turned off - but came a little early than expected for some people.
