Mobile phones and internet access have made staying in contact easier than ever. But they also mean many households now rely on a small number of communication systems for almost everything.
A prolonged power cut, severe weather, flooding, network congestion or a local infrastructure failure could make some of those systems temporarily unreliable.
Emergency communication preparedness is not about assuming every phone mast and internet connection will suddenly fail. It is about having alternatives when the method you normally use is unavailable.
A sensible emergency communications plan combines phones, backup power, different ways of sending messages, reliable sources of information and a simple family plan that still works when technology does not.
Why Emergency Communications Matter
Communication during an emergency serves two main purposes.
The first is staying in contact with other people. You may need to check on family members, tell someone where you are or arrange where to meet.
The second is receiving reliable information. During severe weather, flooding, a major power cut or another local emergency, knowing what is happening can help you make better decisions.
Normal communications can be disrupted in several ways. Electricity failures can affect broadband equipment and eventually mobile infrastructure. Storms and flooding can damage local services. Mobile networks can also become congested when large numbers of people try to call at the same time.
The important point is that disruption is not necessarily all-or-nothing. Your broadband might fail while your mobile still works, or voice calls may be difficult while text messages continue to get through.
That is why emergency communications are best approached in layers.
Don’t Rely on One Communication Method
There is no single perfect emergency communication device.
Instead, build some redundancy into your plans.
For example, your normal communication options might include:
Phone calls → SMS messages → internet messaging → short-range radio → predetermined family plans
Receiving information is another layer. A mobile phone may provide news and official alerts while networks are working, while a battery-powered radio can provide another source if internet access is lost.
These methods do not all need to fail before they become useful.
If broadband goes down, your phone’s mobile data connection may still work. If mobile data is unreliable, SMS might still be available. If you cannot contact a family member at all, an agreed meeting point or fallback plan means you already know what to do.
This is more useful than spending a large amount of money trying to find a single device that supposedly solves every communication problem.
Mobile Phones Are Still Your Most Useful Tool
Despite their limitations, mobile phones should remain at the centre of most household emergency communication plans.
They provide calls, text messages, internet messaging, maps, news, emergency alerts and access to important information from one device.
The obvious weakness is battery life.
During a power cut or other disruption, avoid using your phone unnecessarily. Reducing screen brightness, activating a battery-saving mode and limiting video streaming or other power-hungry activities can considerably extend its useful life.
You should also have at least one way to recharge it without mains electricity.
A charged power bank is one of the simplest options. Households that want more capacity might keep several power banks or a larger portable power station.
A USB charger in your car can provide another option, although you should not run a vehicle unnecessarily in an enclosed space simply to charge electronics.
If you are choosing backup power specifically for phones and other small electronics, see our guide to the Best Emergency Power Banks rather than buying solely on advertised capacity.
Keep Important Numbers Somewhere Other Than Your Phone
Another simple precaution is to write down essential telephone numbers.
Many people no longer know even close family members’ numbers because their phone handles everything automatically.
Keep a printed list containing relevant numbers for family members, schools, workplaces and other important contacts.
That way, losing access to your phone does not mean losing access to your entire contact list.
Calls, Text Messages and Internet Messaging
Different types of mobile communication have different strengths.
Voice calls
A telephone call is usually the quickest way to exchange detailed information.
However, repeatedly calling several relatives during a busy incident wastes battery and may add unnecessary network traffic. A short call to one agreed family contact may be more effective.
If calls are not connecting, constantly redialling is not always the best response. Try another communication method.
SMS text messages
Traditional SMS messages are worth remembering.
They are short, require very little interaction from the recipient and can be useful when making a conversation is difficult.
SMS should not be treated as guaranteed to work whenever voice calls fail. Both depend on mobile network infrastructure, and different outages affect networks in different ways.
However, if calls are proving unreliable or networks are busy, sending a concise text is a sensible alternative.
A useful emergency message might simply include:
- where you are;
- whether you are safe;
- where you are going next;
- when you expect to make contact again.
That communicates the important information without requiring a long conversation.
WhatsApp, Signal and other messaging apps
Internet messaging services can also be extremely useful.
A household WhatsApp or Signal group, for example, allows one person to update several relatives at once.
The limitation is that these services need an internet connection through mobile data or Wi-Fi. If internet connectivity is the problem, they may no longer be available even though ordinary calls or SMS still work.
Use them as another communication layer rather than your only one.
Understand UK Emergency Alerts
The UK’s Emergency Alerts system allows the government and emergency services to send warnings to compatible mobile phones and tablets in an affected area.
Alerts may be used for life-threatening situations such as severe flooding, wildfires or extreme storms.
The system works differently from an ordinary text message. Mobile phone masts in an affected area broadcast the alert to compatible devices connected to UK 4G and 5G networks.
You do not need to register, provide your phone number, install an app or have mobile data or Wi-Fi switched on to receive an alert.
An alert normally causes a loud siren-like sound and vibration and displays instructions on the screen.
Keep your phone’s software reasonably up to date and familiarise yourself with what Emergency Alerts look like.
Most importantly, read the information in the alert and follow the official instructions.
Emergency Alerts are an additional warning system rather than a replacement for radio, television, local news and other ways of informing the public.
How to Get Information Without the Internet
Emergency communications are not just about transmitting information.
Sometimes receiving accurate information is more important.
If broadband and mobile internet access disappear, a radio provides an independent way to receive news and public information.
Options include:
- battery-powered radios;
- rechargeable emergency radios;
- wind-up radios;
- vehicle radios;
- portable radios kept in an emergency kit.
A battery-powered radio is particularly useful because your household broadband router does not need to be working.
Local and national radio broadcasts can provide information about severe weather, transport disruption, flooding and other developing situations.
You do not necessarily need a specialist emergency radio. A reliable portable AM/FM or DAB radio with a sensible backup power option may be perfectly adequate.
For a detailed look at different radio types and power options, see our guide to the Best Emergency Radios for UK Preppers. We’ve also reviewed the FosPower A1 emergency radio if you want a closer look at one popular hand-crank option.
It is also sensible to download or print important information before you need it. Maps, emergency contact information and household plans should not exist only in cloud storage.
PMR446 Walkie-Talkies for Short-Range Communication
Walkie-talkies can provide another useful layer of communication, but their capabilities are often exaggerated.
For most UK households, the simplest option is PMR446, with a great option for preppers being the Motorola Talkabout T82 Extreme walkie talkie.
PMR446 is a short-range radio service operating between 446.0 and 446.2 MHz. Compliant PMR446 handheld radios can be used in the UK without obtaining an Ofcom licence, provided they meet the relevant requirements.
UK PMR446 equipment is limited to low-power operation, with a maximum effective radiated power of 0.5 watts. Ofcom describes the service as short-range, simplex, peer-to-peer radio communication.
That makes PMR446 useful for situations such as:
- family members around a large property;
- camping trips;
- walking groups;
- neighbours who have agreed to communicate;
- two vehicles travelling together;
- short-distance communication during a local mobile outage.
The important word is short-distance.
Walkie-talkie packaging sometimes advertises very impressive maximum ranges. Real-world performance can be considerably lower.
Buildings, hills, woodland and other obstacles can reduce radio range. Communication between two people in open countryside with clear line of sight may be very different from communication between houses in a built-up area.
PMR446 channels are also shared. Other users may be able to hear your transmissions, so never assume a conversation is private.
Both people obviously need working radios and must know which channel to use.
For these reasons, PMR446 should be viewed as a useful local communication tool rather than a replacement for mobile networks. Read our guide to The Best Walkie Talkies for Preppers for more information.
Make a Family Emergency Communication Plan
Equipment is much more useful when everyone already knows how it will be used.
Your household communication plan does not need to be complicated. In fact, simpler plans are often better.
Decide who contacts whom
If several family members are separated, decide how information should be passed around.
One person could act as the main household contact rather than everyone repeatedly calling everybody else.
This can be particularly useful if children, elderly relatives or family members at work are involved.
Agree meeting points
Decide where household members should meet if normal communication is unavailable.
You might have one meeting location close to home and another outside your immediate neighbourhood.
Choose places that everybody can identify easily.
Decide what happens when nobody can make contact
This is where a communication plan becomes particularly useful.
If nobody can phone or message anybody else, each person should already have a rough idea of what to do.
Depending on your household, that might mean remaining at school or work until normal arrangements resume, returning home when safe, or going to an agreed meeting point.
The precise plan matters less than everybody understanding it beforehand.
Our Family Emergency Plan guide covers household contacts, meeting points, children and wider emergency planning in more detail.
Keep Important Information Available Offline
Modern phones provide easy access to enormous amounts of information, but they can encourage us to store everything online.
Keep a small amount of essential information available without internet access.
A household emergency sheet could contain:
- family telephone numbers;
- home and family addresses;
- school and workplace contact information;
- GP and pharmacy details;
- relevant utility emergency numbers;
- insurance contact information;
- agreed meeting locations;
- useful local radio information;
- details of your household communication plan.
A paper copy is inexpensive and does not need electricity.
You can also keep important documents and information stored locally on a phone or other device for offline access.
Use some common sense about sensitive information. An emergency folder does not need to contain unprotected banking passwords, PIN numbers or a complete collection of confidential personal data.
The aim is to preserve access to useful information, not create a security problem.
A Basic Emergency Communications Kit
You do not need a room full of radio equipment to create useful communications resilience.
A practical household kit might include:
- mobile phones;
- appropriate charging cables;
- one or more charged power banks;
- a vehicle USB charger;
- a battery-powered or rechargeable radio;
- spare batteries where required;
- PMR446 radios if they suit your plans;
- a printed emergency contact sheet;
- a notebook and pen;
- a local paper map where useful.
What you need depends on your household.
Someone living alone in a city flat may have very different communication requirements from a family living in a rural area.
Do not buy equipment simply because it is marketed as emergency gear.
Start with the problem you are trying to solve, then choose equipment that supports your plan.
Test Your Communications Plan Before You Need It
Emergency equipment that sits untouched in a cupboard for years may not work when you expect it to.
Occasionally check your communication kit.
Make sure power banks are charged, cables still work and disposable batteries have not leaked or expired.
Turn on your emergency radio and confirm that you can receive useful stations.
If you own PMR446 radios, test them in the places where you realistically expect to use them. Finding out that two radios cannot communicate reliably between the locations you had planned is far more useful during a test than during an emergency.
Check your printed contact list too. Phone numbers, schools, workplaces and family arrangements change over time.
Finally, make sure the people involved actually know the plan.
There is little value in an agreed meeting point that only one member of the household remembers.
Emergency Communications Checklist
A basic household communications plan does not need to be complicated.
Before an emergency:
- keep phones charged;
- maintain some backup power;
- know how to conserve phone battery;
- keep important telephone numbers on paper;
- use calls, SMS and internet messaging as complementary options;
- understand UK Emergency Alerts;
- have another way to receive news;
- consider PMR446 radios if you have a genuine short-range communication need;
- agree household contacts and meeting points;
- decide what everyone should do if communication fails;
- keep important information available offline;
- test your equipment periodically.
Most of these preparations cost very little.
Build Layers, Not Dependencies
Good emergency communications are built around redundancy rather than one supposedly perfect device.
For most UK households, a charged mobile phone will remain the first and most useful option. Backup power helps keep it running. SMS and internet messaging provide alternative ways to communicate, while a portable radio gives you another way to receive important information.
PMR446 radios can add useful short-range communication where appropriate.
But the final layer requires no technology at all.
If everyone in your household knows who to contact, where to meet and what to do when contact is impossible, you are no longer completely dependent on a working phone network.
That simple combination of equipment, alternatives and planning can make your household considerably more resilient when normal communications are disrupted.
