My wife has 15PM. She does not have a watch nor does she want one. However we are getting “up there” in age and fall detection is a motivating factor. And she does not like dragging her iPhone around, especially while doing yard work. If she has a GPS only (no LTE) version of SE (or even regular) watch and is not in wifi range, will fall detection call emergency service, presumably via satellite? Or, could she take a walk with a non-cell watch and still have operational fall detection?
