A raised voice can make things worse. A visible phone call can provoke. For many people — someone walking home, a nurse on a house call, a woman who hears a stranger at the door — the safest thing is to reach for help without making a sound. These are the moments SilentCall was built for.
Case study · Lone worker
The last house call
Marta is a community nurse. Most days she visits eight homes alone — often people she's never met, sometimes down long rural lanes with no one else around. She loves the work. She just doesn't love the last visit of the day, in winter, when it's already dark.
One evening a patient's adult son had been drinking, and the mood in the room turned. Marta didn't argue and didn't reach for her phone in front of him. On her way to the door, she pressed the SilentCall shortcut in her pocket. It connected, recorded, and — because she didn't cancel — sent the audio to her team lead, who called her two minutes later on a pretext and stayed on the line until she was back in her car. Nothing 'happened.' That is exactly the point.
53 million people work alone across Europe and North America. In the US, healthcare workers face an average of 57 assaults every day.
More moments you might recognise
Illustrative scenarios — the situations SilentCall is built for. Short films coming soon.
The walk home
You're walking home late. Someone on the empty street makes you uneasy. Nothing has happened — it may be nothing — but your instincts are awake. You press the button. If they turn off, you cancel. If they don't, someone already knows where you are and what you're hearing.
A stranger at the door
You're staying in a rented flat, far from home, when you hear a key turn in the lock. Your heart races. It could be the owner. It could be anyone. You don't have to decide who it is before you're safe — you press once, and if it's nothing, you cancel.
Her first night out
Your daughter is old enough to go to the club, and old enough to resent being tracked. You don't want her location. You want to know she's safe. The SilentCall icon on her home screen isn't surveillance — it's a door she can open if she ever needs to.
The solo showing
An estate agent meets a new 'buyer' at an empty property, alone, the address shared with no one. It's a normal part of the job — and one of its quiet risks. Before she unlocks the door, the shortcut is ready. If the viewing feels wrong, help is one press away.
How to call for help if you can't speak — right now
If you are in immediate danger, contact your emergency services first. Here's how to reach them when you can't talk, wherever you are.
United Kingdom
Dial 999, then press 55
Call 999. If you can't speak, listen and press 55 when prompted (or cough or tap the handset). On a mobile, pressing 55 tells the operator it's a genuine emergency and transfers you to the police. Important: staying silent alone is not enough on a mobile — you must press 55.
United States
Text 911 where available
Official guidance is 'call if you can, text if you can't.' Where Text-to-911 is available, you can text your location and emergency to 911. It isn't available everywhere; if your text can't be delivered, you'll get a bounce-back message telling you to call.
European Union
Call 112
112 is the free emergency number across the whole EU. Many countries also offer SMS or app-based access to 112 for people who can't make a voice call — check what's available where you live.
Everywhere
SilentCall — for the in-between
SilentCall doesn't replace 999, 911 or 112. It's for the in-between moments — when you're not yet sure it's an emergency, or when the people you most want to reach are the ones who love you. One silent call records the situation and alerts up to three people you trust.
Emergency numbers and silent-call procedures vary by country and change over time. Always check the official guidance for where you are — links are at the foot of this page.
When you'd rather turn to someone you trust
Not everyone wants the first call to go to an official line. You might simply prefer that the person who hears you is someone who knows you — a sister, a friend, a parent. SilentCall sends your recording to the people you choose, so help comes from someone you trust, on your own terms.
In a life-threatening emergency, please still contact emergency services if you can safely do so.
People also ask
How do you call for help if you can't speak?
You have several options. In the UK, dial 999 and press 55 when prompted. In the US, use Text-to-911 where available. In the EU, call 112 (with SMS or app options in many countries). Services like SilentCall let you place one silent call that records your situation and alerts people you trust — without saying a word.
What is a silent emergency call?
A silent emergency call is a way to reach help without speaking, for situations where talking could put you in more danger. It can mean a silent 999 call using 'press 55' in the UK, Text-to-911 in the US, or a discreet service like SilentCall that records and notifies your trusted contacts.
Does a silent 999 call work on its own?
Not by itself on a mobile. If you call 999 and stay completely silent, your call may be ended. You need to press 55 (or cough or tap) when prompted so the operator knows it's a real emergency. From a landline, background noise can be enough for the operator to transfer you to the police.
What if I don't trust officials?
You can choose trusted people to be your first point of contact. SilentCall sends your recording to up to three people you pick — family or friends — so someone who knows you is alerted. If your life is in danger and you can safely reach emergency services, please still do.
Can SilentCall replace 999, 911 or 112?
No. SilentCall is a complement to your emergency services, not a replacement. Use 999, 911 or 112 for immediate, life-threatening danger. Use SilentCall for the uncertain moments in between, and to make sure the people you trust are informed.
Is SilentCall a recording app?
No — there's no app to install. SilentCall is a dedicated phone number. You call it silently; it recognises your number, records, and sends the recording to your trusted contacts unless you cancel within 40 seconds.

Set it up once. Keep the confidence of knowing someone will always know.
