Talking When the Phone Network Is Down

Radios, walkie-talkies and a family plan

6 minBeginnerUpdated 2026-10-23 Talking When the Phone Network Is Down

You will learn

Keep receiving official information with a battery or wind-up radio
Use licence-free walkie-talkies with realistic expectations
Make a family communication plan that works without phones

⚠️ Always try the emergency number, 112 in Europe, even when your phone shows no service.

⚠️ Follow official broadcasts over rumours, and do not use frequencies that need a licence unless you hold one.

A radio for official news

In a big power cut, storm or disaster, mobile networks can fail or become overloaded within hours, and the internet goes with them. Ordinary FM and AM broadcast radio usually keeps working, because stations have backup power and their signals travel a long way. Keep a battery or wind-up radio at home, with spare batteries, and know the frequencies of your national public broadcaster and local stations. During the Iberian blackout of April 2025 many people in Portugal and Spain relied on exactly this. Listen at set times rather than all day to save power, and trust official sources over rumours.

💡 Write your local station frequencies on a sticker on the radio itself.

Walkie-talkies: what they can really do

For talking within a family or a small neighbourhood, simple walkie-talkies work with no network at all. In Europe, PMR446 radios are licence-free and cheap; in the United States the equivalent is FRS. Ignore the range printed on the box, which assumes perfect conditions. In towns, among buildings, expect often 1 to 3 km. Between open hilltops with a clear line of sight you can get much more. Agree a channel, and a backup channel, in advance, and set check-in times, for example on the hour for five minutes, so radios can stay off between calls and save battery. Keep messages short and test the radios every few months.

💡 Practise once with the whole family so everyone knows how to press, wait and speak.

When the phone still half works

A struggling network often fails for calls before it fails for text. Short text messages need very little capacity and are stored and retried, so a text can get through when a call will not. Keep messages brief and say where you are and whether you are safe. Save battery: lower the screen brightness, close apps, and switch the phone off between checks. Calls to the emergency number, 112 in Europe, may still connect on another operator's network even when your own has no service, so always try. Do not tie up the network with unnecessary calls.

A family plan and other options

Technology fails, so the most reliable tool is a plan agreed in advance. Choose a meeting point near home and one further away in case your area is evacuated. Pick an out-of-area contact, a relative in another region who everyone reports to, because long-distance lines may work when local ones are jammed. Write important numbers on paper and keep a copy in every bag and wallet, since few of us remember them. Amateur, or ham, radio can reach much further and has a long record in emergencies, but it requires a licence and some study. Finally, remember the simplest signals: a whistle, three blasts for help, and a torch or bright cloth to be seen.

💡 Ask yourself: if every phone died right now, where would my family meet?

Check yourself

Why keep a battery or wind-up radio at home?

FM and AM broadcasts reach you with no network and carry official instructions.

What range should you realistically expect from PMR446 radios in a town?

Buildings block signals. More range is possible between open hilltops, but plan for a few kilometres.

The network is overloaded and your calls fail. What should you try?

Texts need little capacity and are retried, so they often get through when calls do not.

What is the point of an out-of-area contact?

Local networks jam first. A contact elsewhere links scattered family members.

Try it for real: Build your no-network kit

Check you have a battery or wind-up radio and spare batteries, and note your local station frequencies
Write key phone numbers on paper for every family member
Agree a near and a far meeting point and an out-of-area contact
If you have walkie-talkies, agree a channel and check-in times, then test them
