Emergency alert system is tested on mobile phones across England as part of plan to warn people about terror attacks, flooding and fires
- The new alert system is only compatible with masts on the 4G and 5G network
- It will also only work for iPhones running iOS 14.5 or later and Android 11 or later
- The test was specifically for Android users connected to some mobile networks
- A later test next week will be for iPhone and Android but only users in Reading
- The government hasn’t said which networks are involved in this new testing
- The emergency alert system is expected to be rolled out by the end of summer
Some Android mobile phone users in England got an ’emergency alert’ from the government today, as part of a nationwide test of a new warning system.
It was the first of two tests this month, with the second also including iPhone users, but restricted to people in Reading. Both are purely a test and not a real warning.
The emergency alert system has been set up to give the government a way to quickly warn people of an impending risk to life from things like flooding or fire.
Few people were expected to receive the alert, which was triggered between 13:00 BST and 14:00 BST and made it clear it was a ‘test of the Emergency Alerts service’.
It said: ‘This is a mobile network operator test of the Emergency Alerts service. You do not need to take any action. To find out more, search for gov.uk/alerts.’
The warning was also able to trigger a ‘loud siren-like sound’ on user’s device and is based on systems built natively into iOS and Android with an ‘opt-out’ option.
When fully rolled out it will only work for users connected to 4G and 5G masts and people with an iPhone running iOS 14.5 or Android running version 11.

Flood alerts are one of the things the government will user the alert system to warn users about and it can be restricted to the local area
EMERGENCY ALERT SYSTEM DEVICE COMPATIBILITY
The Emergency Alert system uses Cell Broadcast technology.
This system is only compatible with fairly recent versions of both iOS and Android, as well as newer masts.
It will only work on 4G and 5G masts and early 2G and 3G don’t include the necessary technology.
It is only available for users with phones running iOS 14.5 or Android 11.
iPhone 6s and above can run iOS 14.5.
Some older Android phones with a Wireless Alerts setting will also potentially receive the warning.
It will appear as a text message and may be accompanied by a loud siren-like noise coming from the phone.
The government hasn’t shared an update on the results of the latest test, but if both go to plan the system will be rolled out nationwide.
Users will be able to opt out in their phone settings but the most severe alerts will still get through.
The system makes use of mobile infrastructure – specifically 4G and 5G – sending the message to all devices connected to specific masts rather than to mobile numbers.
The same type of system is already widely in use in New Zealand where it has been credited with saving lives around national emergencies.
The government has already tested the new UK system in East Suffolk where residents were sent a ‘test alert’.
The Government alert website explained that ’emergency alerts will warn you if there’s a danger to life nearby. ‘In an emergency, your phone or tablet will receive an alert with advice about how to stay safe.’
As well as natural disasters like fire, flooding and extreme weather events, the alert system can warn of impending terror attacks or virus outbreaks.
In March 2020 the government worked with all mobile networks to send an automated text message to inform people about lockdown rules and have sent flood warning tests prior to this alert in coordination with the mobile networks, but this acts as a standalone service the government or emergency service officials can trigger themselves.
The new system works with iOS 14.5 or later and Android 11 or later, which have the emergency system infrastructure built in.
It may also work on older Android devices that have a Wireless Alerts setting. It is also restricted to 4G and 5G networks, it won’t work on 2G and 3G systems as the Cell Broadcast technology hasn’t been integrated into those masts.
Once fully implemented – likely by the end of summer this year – emergency services and government bodies will be able to use it in times of emergency.

It can work at both a local and national level, with any test making it very clear that it isn’t a real emergency.
While users can opt out of the alerts, the government has urged people to keep it switched on as it will include more than a simple flood alert.
‘Emergency alerts are broadcast from mobile phone masts. Every compatible mobile phone or tablet in range will receive an alert,’ the government explained.
A number of countries are already using emergency alert systems to warn users of everything from impending fires and floods to Covid-19 restrictions
The government does not need your phone number to send you an alert.
The test on June 29 will be restricted to iPhone and Android users in Reading, Berkshire with a test alert sent between 13:00 BST and 14:00 BST. Users are told they won’t have to do anything and it will be clear this is a test.
It will say: ‘The UK government is testing Emergency Alerts in Reading, Berkshire. Emergency alerts tell you what to do if there’s a life-threatening event nearby. To find out more, call 0808 1697692 or search for gov.uk/alerts’
HOW TO OPT OUT OF EMERGENCY ALERTS
The government has urged people to keep emergency alerts turned on due to the fact they could save lives and turning them off could put lives at risk.
However, as it uses a system built into both iOS and Android, opting out is simply a case of changing an option within settings.
You can opt out of some emergency alerts, but not the most important ones, those will still be forced through to your device.
You cannot opt out by subject, only by how serious the emergency is. If you opt out because you do not want flood warnings, for example, you might miss alerts for fires and terrorism.
Android: To opt out, search your settings for ‘emergency alerts’ and turn off Severe alerts.
If you have an Android device, there’s a small chance you may get test alerts from your mobile network operator.
iPhone: To opt out, search your settings for ‘emergency alerts’ and turn off Severe alerts.
