Reminder: at 3pm on Sunday there will be a test of the Emergency Alert system across the UK.
You will receive a message on the home screen of your mobile phone, along with a sound and vibration for up to ten seconds.
You do not need to take any action – the sound and vibration will stop automatically after ten seconds. All you need to do is swipe away the message or click ‘OK’ on their phone’s home screen – just like for a ‘low battery’ warning or notification – and continue to use your phone as normal.
