When Mobile Networks Fail: How to Communicate During a Crisis

August 18, 2026

Most people receive emergency information through a phone. Warnings arrive as notifications, municipalities publish updates online, families use messaging apps, and maps guide people towards open roads, shelters or healthcare services.

That system works until electricity, mobile networks or internet access fail.

A major storm, flood, wildfire, cyberattack, technical failure or security-related incident can disrupt several services at the same time. Mobile networks may become overloaded even when the infrastructure remains intact. Batteries and backup power eventually run down. Digital information may be unavailable, delayed or difficult to verify.

Preparing for this situation does not require specialised equipment. It requires a simple emergency communication plan, information stored outside your phone and a clear understanding of where local authorities will communicate if normal digital channels are unavailable.

Why communication failure deserves its own plan

During an emergency, information affects almost every other decision. You may need to know whether to remain at home, evacuate, boil water, avoid a particular road or seek medical assistance elsewhere.

When trusted information is unavailable, several problems develop quickly:

Rumours can spread faster than verified updates.
Families may travel unnecessarily while trying to locate one another.
Residents may repeatedly call emergency numbers for non-emergency information.
People may follow outdated evacuation instructions or maps.
Vulnerable residents can become isolated.
Unofficial social media posts may be mistaken for current public guidance.

Communication preparedness is therefore not simply about owning a radio or walkie-talkie. It is about creating several reliable ways to receive, verify and share information.

What Norway’s latest preparedness data shows

The Norwegian Directorate for Civil Protection (DSB) has made the loss of mobile networks and internet access the central theme of Egenberedskapsuka 2026.

The decision reflects a significant preparedness gap. DSB’s latest population survey found that:

Only 14% know whether their municipality has a fixed meeting point for residents during major accidents or crises.
Only 33% know where to find information from their municipality during a crisis, down from 41% the previous year.
Only 37% have considered how they would seek help if communication services were unavailable.
Half of the population remains only slightly prepared or not prepared at all to manage for one week if electricity, water, mobile networks or internet access disappear.

The figures show that material preparedness and communication preparedness do not always develop together. A household may have water, food and batteries but still be unable to answer a basic question: where will we obtain verified local information if our phones stop working?

What is a municipal information point?

A municipal information point is a physical place where residents can receive official information when electronic communication is unavailable. Depending on the municipality and event, it may be established in a town hall, school, library, fire station, community building or another accessible location.

Its purpose is not necessarily to replace an emergency shelter, medical centre or general assistance office. Its primary function is to provide verified information and, where planned, receive important enquiries from the population.

DSB recommends that municipalities prepare and exercise these locations. Exercises can include alerting staff, retrieving equipment, opening the premises, recording enquiries and allowing residents to test whether the service is understandable.

Before an emergency, check your municipality’s website or contact it directly and ask:

Does the municipality have designated information points?
Where are they located?
Under which circumstances will they be activated?
How will residents know that a point is operating?
Are there alternatives for people who cannot travel there?

Write the answers down. Do not rely exclusively on a saved web link.

Create a family emergency communication plan

A useful family plan should work even if phones cannot connect, batteries are low or family members are in different parts of the city.

1. Choose two meeting points

Select a primary meeting point close to home and a secondary point outside your immediate neighbourhood. The first can be used for a local evacuation, while the second is useful if the area around your home cannot be reached.

Choose places everyone can identify without digital maps. Consider accessibility, seasonal conditions and whether children can reach the location safely.

2. Select an out-of-area contact

Choose a trusted person who lives outside your local area. During a regional disruption, it may be easier to send information to someone outside the affected network than to contact family members nearby.

Every household member should know the person’s full name and telephone number. Keep it on paper as well as in the phone.

3. Create a printed contact sheet

Your emergency contact sheet should include:

Household telephone numbers.
School, workplace and childcare contacts.
Close relatives and trusted neighbours.
Your out-of-area contact.
Medical contacts and essential health information.
Insurance and utility emergency numbers.
Municipal crisis-information channels.
The addresses of your meeting points.

Place copies in your emergency kit, wallet, vehicle and children’s school bags where appropriate. Review the information at least twice a year.

4. Agree on simple messages

If mobile service is unstable but not completely unavailable, text messages may be delivered when calls cannot connect because they require less network capacity. Keep messages short and factual.

A useful format is:

Name — location — condition — next action — next update time.

For example: “Anna — at school — safe — staying here — will try again at 16:00.”

Avoid repeatedly sending large images, videos or non-essential messages during network congestion.

5. Decide when not to travel

Families often assume everyone should immediately try to return home. That may be unsafe during flooding, wildfire, severe weather, violence or a transport disruption.

Agree in advance that family members will follow official instructions and remain at a safe school, workplace or public facility when travelling would increase the risk. A meeting plan should reduce unnecessary movement, not create it.

Build several ways to receive official information

No single communication channel is reliable in every scenario. Use a layered system.

Emergency alerts

Keep official emergency alerts enabled on your phone. They may still work during some disruptions, but should never be your only source.

Battery-powered DAB radio

In Norway, NRK P1 is the national emergency channel. A battery-powered DAB radio allows you to receive public information when household power and internet access are unavailable. Store spare batteries and test the radio periodically.

Vehicle radio

A car radio can provide another way to receive broadcasts, but avoid running a vehicle inside a garage or enclosed space because of carbon-monoxide risk. Fuel availability may also be limited during a prolonged disruption.

Municipal information points

Know the planned locations in your municipality and how they will be activated. If no public information is available, ask the municipality before a crisis rather than waiting until one occurs.

Trusted community contacts

Housing cooperatives, neighbourhood groups, schools and local volunteer organisations can help pass on verified information. They should have clear rules: identify the official source, include the time of the update and distinguish confirmed information from observation.

Two-way radios

Walkie-talkies can support short-range communication between household or group members, but range varies significantly with buildings, terrain, equipment and local conditions. They do not provide official information and should be treated as a supplementary tool, not a replacement for public warning channels.

How to verify information during an outage

An information vacuum makes misinformation more likely. Before acting on an important message, ask:

Who issued the information?
At what time was it issued?
Does it apply to my exact area?
Has it been confirmed through an official broadcast or information point?
Is it a current instruction or a report from earlier in the event?

When sharing an update, always include its source and time. Do not add assumptions. If something is unconfirmed, say so clearly.

Avoid travelling to investigate rumours. This can expose you to danger and interfere with emergency operations.

Include people who may not receive the message

A communication plan is incomplete if it only works for digitally confident adults.

Consider neighbours or relatives who:

Live alone.
Have limited mobility, hearing or vision.
Depend on electrically powered medical equipment.
Do not speak the local language fluently.
Are visiting the area and do not know local systems.
Have cognitive difficulties or need assistance understanding instructions.

Agree on a safe check-in method before a crisis. Do not place yourself at risk or promise assistance you cannot provide, but make sure vulnerable people are included in neighbourhood planning and known to the appropriate support services where consent and local procedures allow.

Exercise the plan before you need it

A communication plan should be tested, not merely written.

Once or twice a year, run a simple household exercise:

Put all phones into airplane mode.
Ask each person where they would go and whom they would contact.
Locate the printed contact sheets and radio.
Find the primary meeting point without using a digital map.
Confirm how official municipal information would be obtained.
Identify any family member, neighbour or essential contact missing from the plan.

Keep the exercise short and realistic. The goal is to find gaps while they are easy to correct.

Emergency communication checklist

Before a disruption:

☐ Identify your municipality’s crisis-information channels.
☐ Find out whether it has physical information points.
☐ Choose primary and secondary family meeting points.
☐ Select an out-of-area contact.
☐ Print essential telephone numbers and addresses.
☐ Keep a battery-powered DAB radio and spare batteries.
☐ Store power banks charged and accessible.
☐ Agree on a short message format.
☐ Include children and vulnerable household members in the plan.
☐ Test the complete plan without internet access.

Preparedness begins before the signal disappears

Digital communication makes modern cities efficient, but it also creates dependency. When mobile networks or internet access fail, the solution cannot be improvised entirely after the outage begins.

Households need information on paper, agreed meeting points and more than one way to receive official updates. Municipalities need information points that have been tested with the public, not only described in internal plans. Communities and workplaces need procedures for passing on verified information without amplifying rumours.
