How does the SOS call work?
You can ask to get a call from the tracker when the carrier pushes the SOS button (and only provided that the SOS button is pushed).
You will get a notification of the SOS call. When opening the notification (with just a click), a pop-up window will appear and offer to get a call from the tracker.
By default, the tracker will call the number that you set up. You can update this number from the pop-up window if necessary. It allows for the first person who gets the notification to take action quickly.
