From April, the government will be able to send emergency alerts to our mobile phones.

A siren will go off, even if your phone is on silent. You won't be able to do anything else on your phone until you turn it off. They plan to test this on 23 April.
I understand the reasons why this can be helpful, and in areas where people need to suddenly evacuate due to wildfires, earthquakes, tornadoes etc it could save lives.
However, personally I don't want it, and have disabled it on my phone.
- Of the emergencies I might experience, I'm not sure I'd want to be alerted to any of them via this method. If a flood or storm is imminent, I'll find out through the usual channels. If a nuclear missile is heading my way, having a few minutes' warning will not help.
- This system is being run / overseen by the UK government, and my trust in them has been somewhat eroded over the past few years.
- I have an anxiety disorder (reasonably well managed with combination of medication and other methods) and I think the cost to my anxiety levels of having my phone suddenly sirenning at me outweighs the negligible probability of this system saving my life.
If you are the kind of calm, resilient person who could have these alarms going off and it not completely throw you, then great.
