An SOS can be sent in two ways:
Press and hold the physical orange key on the side of your device for three (3) seconds, until the device vibrates.
Tap the SOS icon in the app and then press and hold the big SOS icon displayed on the screen for three (3) seconds.
The SOS response centre will be notified that you need assistance together with your location. After this you will be prompted to answer a series of questions that will provide the response centre with more context on your situation. If you cannot complete these your SOS alert will still be responded to. The response centre will try to engage in a two-way chat to gather more information on your situation. Again, if you are unable to respond to these, your SOS alert will still be managed by the response centre.
