Mobile phone owners have been left confused as the emergency alert - which was scheduled to hit the nation's devices at 3pm - sounds on some phones but not others.
The government was trailing a new emergency alert system, supposed to be going out to all mobile phones across the UK. The new national alert system will be used to warn people about dangerous situations, such as floods or during terror attacks, was tested out nationwide on all mobile phones that are compatible with 4G and 5G.
But many people took to social media to voice their concerns that some phones in their homes sounded, while others did not. Many customers of the mobile network Three have particularly complained of not getting an alarm, with hundreds of social media users sharing their lack of emergency notification.
