How TapSOS works

Everything happens through pictures and short questions, so you never need to speak or listen.

  1. Set up your profile

    When you download TapSOS you create an account and add your name, mobile number and address. The app then registers your number with BT's emergencySMS service, which TapSOS needs to work.

    You can also add medical information, such as your blood group, conditions, medication, allergies and whether you are an organ donor, and the people you want as emergency contacts.

  2. Confirm where you are

    Your phone's GPS finds your location and shows it on a map. If it looks wrong, choose Change and enter it yourself.

  3. Choose who you need

    Tap Police, Ambulance, Fire & Rescue or Coastguard. If the 999 handler thinks you need a different or extra service, they will arrange it.

  4. Show what is happening

    Choose the pictures that describe the emergency, then answer a few standard 999 questions, such as “is everyone breathing” or “any serious bleeding”.

  5. Send your alert

    TapSOS turns your answers into a text message. On Android it is sent for you. On iPhone, the message opens ready to go and you tap Send, as you would for any text. You will see it in your messages, addressed to 999.

  6. Help is sent

    A BT 999 handler reads your alert, passes it to the right emergency service and decides on the response. Any questions or updates come back to you by text message.

How your alert reaches 999

Your answers, personal details and medical information are put into a text message and sent to BT, whose handlers pass it to the 999 service over the mobile networks. TapSOS is a different way of communicating with 999, not a separate emergency service.

You need a mobile signal

Because alerts travel by text message, TapSOS only works when your phone has a mobile signal.

United Kingdom only

TapSOS works with the UK 999 service. It will not work abroad, so use the local emergency number when you travel.

Practise first

Practice mode lets you go through every step of an alert without anything being sent to 999. Try it when you first install the app, so you know what to expect.

Only send a real alert in a genuine emergency. Hoax alerts are monitored and can lead to prosecution.
