Chamada de emerxencia cun teléfono sen batería ou sen batería¶

When you need help fast and your battery is at 2 percent, every second counts. A phone that is nearly flat can still make an emergency call, and a phone that is completely dead is not the end of your options. People, payphones, public buildings and some built in phone features can all connect you to emergency services.

This guide explains what to do in the first 30 seconds, how to stretch the last of your battery, how to text emergency services where that is available, and how to get someone else to call for you. It also covers emergency SOS features, payphones and call boxes, and how to prepare so that you never depend on a single phone. If the problem is simply that you need power, see phone battery dies while you are out.

1. Make the call first, not last. If you have any charge at all and need emergency help, call your local emergency number straight away (911 in the United States and Canada, 112 across the European Union, 999 in the United Kingdom). Do not spend your last percent on a map, a photo or a message to a friend. See the list of números de emerxencia para outros países.
2. Say where you are in the first sentence. Give the address, the nearest cross street, a landmark or a road marker. If the call drops, the dispatcher will know where to send help.
3. Stay on the line until told to hang up. Do not end the call yourself. If the phone shuts off, do not panic, because the dispatcher already has your location details and may try to call back.
4. If the phone is dead, ask a person to call. Say, "Please call for an ambulance," or "Please call the police," then give them the location and what has happened.
5. Go to people or a staffed place. Walk toward a shop, hotel, station, restaurant or houses with lights on if it is safe to do so. Staff can call for you, and you are easier for responders to find.
6. Stay where you can be found if you cannot move. If you are injured, in a vehicle or lost, stay put and make yourself visible and audible.

How an emergency call works on a weak phone¶

Understanding a few facts will help you decide what to do when the battery is low.

• An emergency call uses little more power than any other call. A call of a minute or two uses a small slice of battery. A phone at 1 or 2 percent can often finish a short call, though not always.
• Phones try any available network for emergency calls. In many countries, a phone with no signal from its own provider will try other networks for an emergency call. This is sometimes called emergency roaming. Coverage is not guaranteed, and it depends on the country and the local networks.
• A phone may call without a working SIM card or plan. In the United States, the Federal Communications Commission (FCC) requires wireless carriers to pass on 911 calls from any wireless phone, even if it has no active service plan. The same idea applies in many countries through the 112 standard. Do not rely on it, but it is worth trying.
• A locked phone can still call. Most phones show an "Emergency" button on the lock screen. You do not need your passcode.
• Location is sent with the call in many places. Dispatchers in many countries receive an approximate location from the phone automatically. This can be wrong or missing, so always say where you are.
• Weather, buildings and distance matter. A call from a basement, a tunnel, a canyon or a remote area may not connect. Moving to higher or more open ground can help.

Stretching the last of the battery¶

When the percentage is very low and you may need to call, protect what is left. These steps take under a minute and can add many minutes of use.

1. Turn on low power mode or battery saver. It reduces background activity and screen power. Most phones offer this in the control panel or settings.
2. Atenua a pantalla ao nivel máis baixo que poidas ler. A pantalla é un dos maiores desagües.
3. Pecha aplicacións que usan localización, vídeo ou streaming. As aplicacións de navegación e cámara consumen enerxía rapidamente.
4. Desactiva o Bluetooth, o punto de acceso e a wifi se non os usas. Mantén o sinal do móbil activado porque o necesitas para chamar.
5. Non actives o modo avión se precisas chamar. O modo avión apaga a radio. Utilízao só para aforrar enerxía cando non necesites chamar e apágalo antes de marcar.
6. Mantén o teléfono quente. Cando fai frío, méteo nun peto interior. Un teléfono frío pode apagarse con moita carga restante.
7. Limita as chamadas e as mensaxes ao que importa. Mantén cada unha curta.
8. Do not restart the phone. Starting up uses a burst of power and may fail at low charge.

Calling versus texting emergency services¶

A voice call is the best and fastest way to reach emergency services in most situations. Dispatchers can ask questions, hear background noise and guide you through first aid. Text is a backup that is only available in some places.

Text to emergency services¶

Some countries and regions let you send an SMS or text to emergency services, mainly for people who are deaf, hard of hearing or have a speech disability, and for situations where speaking is unsafe. Text can also work when a signal is too weak for a voice call, because a short text needs less signal than a call.

• United States. Text to 911 is available in many areas but not all. The FCC says to call if you can and text if you cannot, and to check whether your local area supports it. If it is not supported, you should receive a bounce back message saying so.
• United Kingdom. The emergency SMS service lets people who are deaf or have a speech impairment text 999, but you must register your phone first. Register in advance by texting "register" to 999 and following the reply. This is also called the 999 text service. A registered phone can then send a text to 999 if it has signal.
• European Union. Many member states offer an SMS option to 112, often for people with hearing or speech difficulties, and the rules vary by country. Check the national emergency services website for your country before you travel.
• Other countries. Availability varies widely. Check your national emergency agency or telephone regulator.

Most emergency text services need you to include your location and the type of help you need, in short plain words. For example: "Fire at 14 Oak Street, third floor, two people inside." Avoid abbreviations, and answer any questions quickly. Do not send photos or emoji.

When texting is better than calling¶

• You are in a situation where speaking aloud would put you at risk.
• You are deaf, hard of hearing or unable to speak.
• The signal is very weak, and voice calls keep dropping.
• The call connects but the dispatcher cannot hear you.

In each case, use text only if you know it is available where you are. If not, try a call first.

Silent calls¶

In some places, if you call the emergency number and cannot speak, the operator may ask you to press a key or tap the screen to show that you need help. In the United Kingdom, you can use the Silent Solution by calling 999 and pressing 55 when prompted if you cannot speak, though it applies to mobile callers only and the operator will tell you what to do. Local rules differ, so do not rely on this in another country.

Emergency SOS features on your phone¶

Modern phones include a few features that can help when you are in trouble.

• Emergency SOS shortcut. On many phones, pressing the side button several times quickly, or a combination of buttons, opens an emergency screen or calls the emergency number. Check your phone's settings to see how it works, and practise once so that you know. Some phones also send your location to saved contacts after the call.
• Satellite emergency messaging. Certain recent phones can send an emergency message by satellite when there is no mobile or Wi-Fi signal. It works only in supported countries, needs a clear view of the sky, and usually takes longer than a regular call. Check your manufacturer's website to see if your phone and region are supported.
• Medical ID and emergency contacts. A medical ID on the lock screen shows allergies, conditions and contacts to first responders without a passcode. Fill it in now, because it can help rescuers.
• Crash detection and fall detection. Some phones and watches can detect a serious crash or a hard fall and start an emergency call. A false alarm can happen, so stay on the line to cancel.
• Location sharing. You can share your live location with a family member or friend in a messaging or maps app. It helps people find you, though it uses battery.

None of these features replaces a charged phone, but they add options. Test your own phone's settings when you are calm. See also Apple Watch and Garmin medical alert and fall detection setup.

Getting someone else to call for you¶

This is the most reliable option when your phone is dead. Most people will help in an emergency, and a few clear words make it easier.

What to say¶

Speak slowly and plainly. Give the person two or three facts and one request.

1. State the emergency. "A man has collapsed." "There is a fire." "I have been in a crash."
2. Indique a localización exacta. A rúa, o nome dun edificio, un marcador de estrada ou un fito.
3. Fai a solicitude. "Chama agora ao teu número de emerxencia local e dilles onde estamos".
4. Pídelles que queden. "Poderías estar na liña e dicirme o que din?"

Who to ask¶

• Anyone walking, driving or standing nearby. Look for people with phones in their hands.
• Persoal en tendas, restaurantes, hoteis, ximnasios, gasolineiras e farmacias.
• Drivers who pull over and security guards.
• Persoal de tránsito e auxiliares de estación. Moitas estacións teñen puntos de axuda e botóns de emerxencia.
• Residents of nearby homes. If it is safe, knock on a door and ask them to call, and stay outside if you do not know them.
• Outro vehículo á beira da estrada. Aceita para chamar a atención desde un lugar seguro á beira, non no carril de circulación.

If one person refuses or does not understand, ask someone else. Language barriers happen, so point, gesture and use simple words such as "ambulance", "police" or "fire". The word "help" is understood in many languages, and the number 112 is known across much of the world.

Seguridade ao preguntar a descoñecidos¶

If you are hurt or in danger, the need for help outweighs the risk of asking. Even so, stay in public view and avoid going into a stranger's car or home. If you feel unsafe, ask them to make the call from where they stand, and keep your distance from anyone who makes you uneasy. A shop or a busy public place is safer than a quiet street.

Payphones, call boxes and help points¶

Payphones have declined in many countries, but they have not disappeared, and some are still in use in stations, hospitals, airports, rural roads and remote communities.

• Emergency numbers are usually free. In many countries, a payphone will connect to the emergency number without coins or a card. This is not true everywhere, so look for instructions on the phone.
• Highway call boxes. Many motorways, bridges and tunnels have emergency telephones or call boxes. They connect straight to a traffic control or emergency centre and give your location automatically. Look for posts at regular intervals along the road.
• Rail and metro help points. Stations usually have intercoms or help points that connect to staff. Look for a button marked "Help" or "Emergency".
• Lift and car park intercoms. Elevators, parking garages and public toilets often have a call button.
• Phone boxes in remote areas. Rural phone boxes or emergency shelters may be the only option, so note where they are on your route.
• Walk to the nearest one only if it is safe. If someone is badly hurt, do not leave them alone unless there is no other choice. Send a second person if you can.

Buildings and services that can help¶

A dead phone is a good reason to go indoors to a staffed place. These locations can place a call, or let you use a phone.

    I --> J
    F --> J

Staying safe while you wait for help¶

After the call is made, the next few minutes matter. Do what you can to keep yourself and others safe and easy to find.

• Stay where you told the dispatcher you are. Moving can make it harder for responders to find you. If you must move for safety, tell the dispatcher or a helper.
• Make yourself visible. Stand near a light, a road sign or a building entrance. Wave a bright item or use a torch if it is dark.
• Make yourself heard. A whistle or a loud voice can help rescuers locate you, in a wood, a building or a flooded area.
• Keep warm and dry. Cover with a coat, a blanket or a bag. Protect yourself from the cold, heat or rain.
• Send someone to the road. If you are in a remote building or a property with a long drive, ask a helper to wait at the road to guide responders.
• Unlock the door and turn on lights. If you are at home and someone is on the way, make it easy for responders to enter.
• Follow the dispatcher's instructions. If you can still speak with them, listen carefully and do what they say.

Memorise the numbers that matter¶

Your contacts are in your phone, which is exactly the thing that failed. Most people know only their own number and perhaps one other. Fix that before the next emergency.

1. Learn the local emergency number for where you live and where you travel. It is usually three digits.
2. Memorise two phone numbers for people you trust. Choose one nearby and one in another city or country. Say them aloud a few times, then write them on a card.
3. Keep a paper card in your wallet or bag. Include names, numbers, your address, allergies, medical conditions and an out of area contact. Our emergency contact card generator pode axudar.
4. Ensina aos nenos os números dos seus pais e o enderezo da súa casa. Practica cun teléfono de xoguete. Vexa fillo perdido para que facer se un neno desaparece.
5. Write numbers inside a bag, phone case or on a wristband when you travel. Use a pen, not a marker that fades.
6. Coñece o teu propio número. Moita xente esquéceo e un estraño pode necesitalo para chamalo.
7. Coñece o teu enderezo e a rúa transversal máis próxima. Cando esteas fóra da casa, obtén o nome do hotel ou lugar no que te aloxas.

Prepara o teléfono antes de que o necesites¶

Algúns pasos de configuración tardan minutos e poden salvarche a vida.

• Turn on the emergency SOS shortcut and practise opening it once. Find the setting in your phone's safety or emergency menu.
• Encha o teu DNI e engade contactos de emerxencia. Asegúrate de que os detalles estean actualizados.
• Enable location services for emergency calls. Most phones do this by default, and you should not turn it off.
• Register for the emergency SMS service if it applies to you. In the United Kingdom, register by texting "register" to 999. Check your country's service for how to sign up.
• Keep your phone updated. Software updates often improve emergency and location features.
• Carry a power bank. A small one gives you at least one more charge.
• Learn how to use airplane mode, low power mode and the flashlight. You may need all three at once.
• Know that SIM less calls may work but not always. Do not rely on an old phone without a SIM unless you have tested it in your area.

Special situations¶

In a car or on the road¶

If your car has broken down or crashed, move to a safe place if possible, switch on your hazard lights and use a roadside call box or a passing driver's phone. Many newer cars have an emergency button or an automatic crash call that connects to emergency services, so check your car's manual. Stay behind a barrier and away from traffic. For more detail, see car breakdown.

Outdoors and in remote areas¶

A dead phone far from help is more serious. Carry a whistle, a torch, a map and a power bank. Three blasts of a whistle or three flashes of a light is a widely recognised distress signal. Stay in one place and stay warm if you are lost.

If you are in a place with satellite messaging or a personal locator beacon, use it. See lost outdoors.

At home¶

If you are inside and your phone is dead, check whether you have a landline, a neighbour who can help or a smart speaker that can call. In a power cut, a cordless landline phone will not work, because the base station needs power, while a corded line usually does. Keep a corded phone if you rely on a landline. See power outage and phone charging at home.

During a disaster¶

Networks can be busy or damaged after a major event. Try text messages, which often get through when calls do not, and keep calls short. Use your emergency number only for real emergencies, and use social media or messaging for non urgent news. For a full plan, see phone dead during a disaster or evacuation.

When you are in danger from another person¶

If you cannot speak safely, try a text to emergency services where it is available, or use the silent call option your country offers. If a phone is not available, go to a place with people and ask for help. Do not confront anyone. Read domestic violence for safety planning.

Worked examples¶

Short scenarios make the steps easier to remember. Read them once and picture yourself in each one.

A fall on a hiking path with 3 percent battery¶

You slip and cannot put weight on your ankle. The phone shows 3 percent and one bar of signal. Dial your local emergency number at once, say the trail name, the nearest junction or marker, and that you cannot walk. Stay on the line, and if the call drops, stay where you are, put on extra layers and blow a whistle in groups of three.

Non use a batería restante para facer fotos da lesión ou buscar primeiros auxilios. Se o despachador segue en liña, pode guiarte. Se o teléfono morre, aínda deu unha localización e unha descrición do problema.

Unha persoa colapsada nun centro comercial e o teu teléfono está morto¶

Non deixes a persoa. Sinala a alguén preto e di claramente: "Ti, coa chaqueta azul, chama agora ao número de emerxencias". Apuntar a unha persoa funciona mellor que preguntarlle a unha multitude. Envía outra persoa á entrada para atoparse coa ambulancia e envía unha terceira para atopar un desfibrilador, que adoita ser unha caixa montada na parede marcada cun símbolo de corazón. Vexa RCP para que facer mentres esperas.

A house fire at night with a dead phone¶

Saca a todos primeiro. Non volvas a buscar o teléfono. Unha vez que esteas fóra e a salvo, vai á porta dun veciño ou pídelle a un transeúnte que chame ao teu número de emerxencia local. Indique o enderezo e di se aínda hai alguén dentro.

A car crash on a rural road¶

Switch on the hazard lights, move away from the traffic if you can, and watch for the next car. Wave down a driver from a safe place on the verge and ask them to call. If you are near a highway call box, use it. When you speak with the dispatcher, give the road name, the direction of travel and the nearest kilometre or mile marker.

Feeling unsafe in a quiet street¶

Walk toward lights and people. Go into a shop, a petrol station, a pharmacy or a restaurant and tell the staff you feel unsafe and that your phone is dead. Ask them to call the police or a trusted contact for you. Stay inside until help arrives or you feel safe.

Common mistakes to avoid¶

• Spending the last battery on something else. Call first, then do everything else.
• Hanging up before the dispatcher says so. Stay on the line unless the call drops.
• Failing to give a location. Say it first.
• Assuming text works everywhere. Check beforehand.
• Using airplane mode and forgetting to turn it off. You cannot call in that mode.
• Walking away from the place you reported. Stay put unless you are in danger.
• Testing the emergency number. It wastes resources.
• Relying on contacts stored only in the phone. Keep a paper copy.

Preguntas frecuentes¶

Can I call emergency services with a dead phone?¶

A completely dead phone cannot make a call, so the best option is to ask another person to call for you. If the phone has even a little charge, dial your local emergency number first and keep the call short. Many phones will try any available network for an emergency call, even without a working plan.

Is texting emergency services better than calling?¶

A voice call is better in most cases, because the dispatcher can ask questions and hear what is happening. Text is useful if you cannot speak safely, if you are deaf or have a speech disability, or if the signal is too weak for a call. Text to emergency services is not available everywhere, and in the United Kingdom you must register first, so check your local service in advance.

Do payphones still work for emergencies?¶

Where payphones still exist, many can dial the emergency number without coins or a card, though this depends on the country and the operator. Look for instructions on the phone. Highway call boxes, station help points and lift intercoms are also good options.

What is the most important thing to say on an emergency call?¶

Say where you are first, because help cannot arrive without a location. Then say what has happened and how many people need help, and stay on the line until the dispatcher tells you to hang up. If your phone dies mid call, the dispatcher may already have enough information to send help.
