On Sunday 23 April, the government will test a new emergency alert system. This means your mobile phone or tablet may play a loud siren-like noise and vibrate, even if it is switched to silent. The sound from the message might shock or startle you or a loved one you’re caring for. But remember it is just a test.

It is possible to switch off the alert in your settings. If you need further help doing this, our friends at Refuge have provided detailed visual instructions.

You can find out more about the alert on the government’s website.
