There were plenty of warnings about the government's first nationwide test of the public alert system, but that didn't stop it scaring people across the country. Tens of millions of people's phones sounded a high pitched alarm at 3pm on Sunday.
And this Welsh woman's reaction was all of us when it went off.
Emma Mears, from Pembrokeshire, was looking at her phone to read about the alert, still jumped when it went off.
She said: "I knew it was coming - but it still scared the s*** out of me! I was sat on the sofa with my husband, and we thought - this is quite a significant thing to happen, let’s film it.
"So my husband started filming me and just as I was talking about it - it went off. “I absolutely s*** myself haha. I didn’t expect it to be so loud! I almost threw my phone across the room.”
Another mum from Cardiff was driving when it went off said: "I had forgotten it was happening so when it went off, I got such a shock. The children were asking what it was and I had to pull over and take a moment before carrying on."
The alert was sent to every 4G and 5G device across the UK, and lasted about 10 seconds. Some people would not have received the alert if their phone was not supported.
The government said the alert would have reached about 90% of mobile phones in the UK. The alert would not have worked on older phones that are not 'smart-phones'.
The message read: "This is a test of Emergency Alerts, a new UK government service that will warn you if there's a life-threatening emergency nearby. In a real emergency, follow the instructions in the alert to keep yourself and others safe. Visit gov.uk/alerts for more information. This is a test. You do not need to take any action."
People in Wales also received the test in Welsh. However, the message in Welsh included an error. While in Welsh it noted "in a real emergency, follow the instructions in the alert to keep yourself and others safe", the word for "safe" was translated to "yn Vogel" rather than "yn ddiogel".
As many Welsh speakers and learners may know, the word "Vogel" has no meaning in Welsh and more specifically the letter "v" is no longer included in the modern day Welsh alphabet. The correct translation would be "yn ddiogel", which means "safe". Some people took to social media to point out the error, with one Twitter user pointing out that the word "Vogel" actually means "bird" in German and Dutch.
A UK Government spokesman said: "A technical error caused one word in the Welsh language version of the emergency test alert to be misspelt. The fact that this occurred in a test alert will mean we can rectify it in future."
