UK Emergency alert system launched

A test to deliver the message and alarm to certain cellphone users failed but millions received both. The emergency notifications are intended for usage in severe weather, flooding and wildfires once fully operational. During the first statewide test of the government's new public alert system millions of mobile phone users received a message and a loud siren. However many people on Sunday received the alert at 2.59 pm one minute earlier than anticipated while some claim they got something at 10 pm or never.

The government's translation of the alert sent out in Welsh contained a spelling error in Wales. A representative for the mobile phone network acknowledged that not all of its users had gotten the message. We are carefully working with the Government to examine why and make sure it doesn't happen when the network is in use a spokeswoman said.

A tiny percentage of mobile customers on some networks did not receive it the Cabinet Office said adding that it would review the findings of the UK wide test. We have effectively finished the test of the UK wide Emergency Alerts system, the largest public communications exercise of its kind ever done a UK government spokeswoman said. We are collaborating with mobile network operators to assess the results and any lessons gained. A message informing customers about the service intended to alert them if there is a life-threatening emergency nearby was sent along with the recognizable sound and vibration.

Every 4G and 5G smartphone in the UK received a 10-second alert. People were instructed to swipe the notification away without further action. According to government guidelines consumers would not receive warnings if their phones were off or in airplane mode linked to a 2G or 3G network or only connected to wifi or incompatible phones. They also would only receive notifications if their phones were compatible.

The test was intended to familiarise the public with the warnings appearance and sound in case they need to be broadcast during future emergencies. It's designed to be applied in severe weather, flooding and fires.The deputy prime minister Oliver Dowden said "It's the sound that just might save your life."

However some have claimed that the warnings themselves could endanger people's lives particularly inattentive drivers and victims of domestic violence who retain a secret phone. Sports arenas, theatres and movie theatres were among those organizing how to prevent disturbance when the test was conducted on Sunday.

What is the technology's mechanism?

Mobile phone masts transmit emergency warnings compatible with all 4G and 5G phone networks. This is distinct from how lockdown orders were distributed by the government during the pandemic when SMS messages were delivered to specific phone numbers.

It implies that whoever sends the alert doesn't need your phone number so you don't have to respond and won't get a voicemail if you miss it. Additionally no geographic or other data will be gathered.

Additionally it implies that tablets and wearables with individual data plans could receive notifications. An alert can be tweaked depending on geography so that the people of Manchester do not need to hear information about life threatening flooding in Cornwall. Anyone within a mast's range will receive an alert.

Will notifications be utilized frequently?

According to ministers alerts will only be delivered in life threatening circumstances.

People who do not want to get the warnings can turn off their phones or put them in flight mode in their device settings but the authorities anticipate that many people will leave their phones on.

Governments have adopted more of these systems in recent years since the demand for quick and direct communication with the public has increased due to pandemics and climate related events.

A directive from the EU mandates that each member state have a phone based public warning system.
