//A siren-like alert will be sent to mobile phone users across the UK next month to test a new government public warning system.//
//Phone users will have to acknowledge the alert before they can use other features on their devices.//
//A message will appear on the home screens of people's devices during the test, with vibration and a loud warning sound that will ring for about 10 seconds, even if the phone is set to silent.//
//People can opt out by searching their device settings for emergency alerts and then turning off severe and extreme ones. Officials say the alerts could be life-saving, though, advising against switching them off.//
Anyone turning the alerts off, I am.
