This is the part of Orbit we care about most. Here is everything that happens, in order, from the moment somebody presses the button.

When a push notification is not enough, Orbit picks up the phone. Life360 also reaches contacts by phone, via a third-party dispatch centre on its paid tiers in five countries; Orbit calls your own people directly, to any number in any country, and shows you the delivery log afterwards.
An SOS opens a working space, pre-loaded with everything a responder would otherwise have to ask for. The summary line at the top is written by Orbit, not by a person, and the What We Know panel under it is live — incident type, who is responding, last known location, battery, and their latest heart rate, blood oxygen, blood pressure and glucose.
While it is live, everyone in the Nest carries the same banner — Your SOS Is Active · Help is on the way — and the person who raised it ends the whole thing with one tap on I'm Safe.
