Emergency alert systems around the world occasionally get tested by governments making changes to the infrastructure. As part of the setup of a new system in the United Kingdom, people within the country will experience an alert broadcast on Sunday.
At 3p.m. BST, 10.a.m. Eastern, smartphones and cellular-equipped tablets using 4G and 5G networks in the UK will receive a message from the Emergency Alerts system. The alert itself will consist of a “loud siren-like sound” and a vibration lasting ten seconds, with some devices also reading the alert aloud, according to the government website.
