This weekend, mobile phones in the UK will be sent a
test Emergency Alert at around 15:00 on Sunday 7th September 2025, the test alert will be sent to all compatible 4G and 5G mobile phones and compatible tablets across the UK.
The Emergency Alerts system is used to warn if there’s a danger to life nearby, including extreme weather. It allows vital information and advice to be sent to people rapidly in an emergency.
Regular testing ensures the system is functioning correctly, should it be needed in an emergency and the test will function like a real life Emergency Alert.
Emergency Alerts work on all 4G and 5G phone networks in the UK. Your mobile phone or tablet does not have to be connected to mobile data or wifi to get alerts. However, you will not receive alerts if your device is: turned off; connected to a 2G or 3G network; Wi-Fi only; or not compatible.
