WHAT THE GUIDANCE SAYS

Quiet the phone,
keep what matters.

Silent mode is not the same as switched off.

Ordinary calls and messages go quiet, but a UK Emergency Alert is designed to sound even on silent. Here is what official guidance says about muting your phone at night, at the wheel and in a real emergency.

ON SILENT but still listening

  • Silent at night
  • Hands off at the wheel
  • Alerts left on
  • A quieter phone, safely

THE SHORT ANSWER

Mute the noise,
not the warnings.

Three places where muting comes up.
Official guidance says something useful about each.

EMERGENCIES

Alerts sound anyway

GOV.UK says an Emergency Alert may make a loud siren-like sound, even if your phone is set on silent, for about 10 seconds.

Will it reach you?

DRIVING

Hands off the phone

It is illegal to hold and use a phone while driving. Even an emergency alert should wait until you have stopped somewhere safe and legal.

Set it up first

SLEEP

Silent and face down

NHS sleep tips include putting your phone on silent to avoid interruptions and placing it face down to reduce light.

A QUICK PHONE CHECK

Will an emergency alert
reach your phone?

Pick the state your phone or tablet is in. The bar shows how likely a UK Emergency Alert is to reach it, according to GOV.UK.

Alert check

Choose your phone's state
On silent, switched onSounds anyway

An alert may make a loud siren-like sound even on silent, vibrate or read the alert out. The sound and vibration last about 10 seconds.

In airplane modeMay be missed

GOV.UK says you may not receive alerts if your device is in airplane mode.

Wifi only, 2G or 3GNo alert

Alerts go out over 4G and 5G networks. A wifi-only device, or one connected to a 2G or 3G network, will not receive them.

Switched offNo alert

A phone that is turned off will not receive alerts. The emergency services have other ways to warn people when there is a threat to life.

Based on GOV.UK guidance on how Emergency Alerts work. Alerts work on iPhones running iOS 14.5 or later and Android 11 or later.

TWO NUMBERS WORTH KNOWING

Built to be heard,
even on silent.

One figure on how many phones an alert can reach,
one on how long it sounds.

≈ 90%

Mobile phones in an area an alert can reach

Before the 2023 national test, the government said Emergency Alerts can get urgent messages quickly to nearly 90 percent of mobile phones in a defined area when there is a risk to life.

How long the siren and vibration last

GOV.UK says the sound and vibration last for about 10 seconds. The UK-wide test at 3pm on Sunday 23 April 2023 sounded for up to 10 seconds.

THE SOUND · GOV.UK

The government says alerts will be used very rarely, only where there is an immediate risk to life, so people may not receive one for months or years.

FOUR THINGS TO SET UP

A quieter phone,
without missing the big one.

None of these needs a new phone or an app. They are settings and habits that fit the official guidance.

  • Find your alert settings

    Search your settings for 'emergency alerts'. GOV.UK advises keeping severe and extreme alerts switched on for your safety.

  • Keep the software updated

    GOV.UK says to make sure your device has the latest updates so it is compatible with Emergency Alerts.

  • Go hands-free before you drive

    Set up a mount, voice command or a headset before you set off. A mount must not block your view of the road.

  • Silent and face down at bedtime

    The NHS suggests putting your phone on silent and face down, and avoiding screens for an hour before bed.

A CONCEALED PHONE

When an alert
could put you at risk.

Because an alert sounds even on silent, it could reveal a hidden phone. GOV.UK says victims of domestic abuse with a concealed phone may find it appropriate to turn alerts off.

On an iPhone, go to notifications and turn off 'severe alerts' and 'extreme alerts'. On Android, search settings for 'emergency alerts' and turn off the same two. Switching the phone off also stops alerts.

Questions

Questions people ask

Will an emergency alert go off if my phone is on silent?

It may. GOV.UK says your phone may make a loud siren-like sound even if it is set on silent, vibrate or read the alert out, for about 10 seconds.

Do I need to sign up or give my number?

No. GOV.UK says alerts are free, need no sign-up or app, and the government does not need your phone number or location to send one.

What should I do if an alert arrives while I am driving?

Do not read or respond to it while driving. Find somewhere safe and legal to stop first, or listen to live radio news if there is nobody else to read it.

Can I use my phone at traffic lights?

No. GOV.UK says the hand-held rule still applies when you are stopped at lights or queuing in traffic. The penalty is 6 points and a £200 fine.

Does putting my phone on silent help me sleep?

The NHS lists putting your phone on silent to avoid interruptions, and face down to reduce light, among its tips for sleeping better.
