I'm also concerned with how this feature will be made available in countries and not in mountains ranges. Like 'France' I'm near the Alps, and enforcing a strict geofencing wouldn't make sense in here. Will the iphone just check your GPS position to enable this functionality or not ? Or will it use the country of your SIM ? Areas with poor coverage in 'France' are mostly mountains. And mountains are (unenforced and hardly marked) border regions. On some hikes in the Alps, you're technically walking in and out of France and Italy. Mt Blanc is a conflicted border between both, and Mt Chenaillet, a popular destination for rock fans, is nearly on the border, for example. And as the border doesn't exist, you can also just technically spend a day in any other country without any preparation ! The same can be seen in the mountains between France and Spain. And nearly any mountainous area in the world, I believe. So I'm just worry that this service will be 'available in France', but won't work when you are on the 5m of the track that are ackchyually in Italy according to legal maps, even if French rescue would be allowed to come to you if you call them. It will feel weird and confusing when this functionality will be reliable only on some mountains, or even mountain sides, but not others, despite the fact they're in the same range.
