Apple bills Family Setup as a way for "the entire family to benefit from the important health and safety features of Apple Watch, like Emergency SOS, while Maps, Siri, Alarms, and the App Store provide greater independence without needing an iPhone."
The added benefit from the perspective of a parent is that this lets them keep tabs on their child's/children's location and they can even set up automatic location notifications so that they know when their kids have arrived at school (or the like) safely.
Family Setup is compatible with cellular models of Apple Watch Series 4 and up (including Apple Watch SE), running on watchOS 7; with 18 carriers across 12 countries supporting the feature globally at launch.
In the UK, only EE currently supports Family Setup, or rather, will support it as of 17 September - a day after the feature's global launch.
EE will offer the Apple Watch SE and Series 6 from 17 September but already sells cellular models of the Apple Watch Series 3, Series 4 and Series 5 on cellular plans from £20 a month.
