I’m going to be traveling to some more remote places around the world in the near future. So I’m looking to get this Garmin Inreach device. This device does a lot of things including sending messages when cell towers are down in urban areas, or if the government shuts off cell service. This will be critical gear for me to communicate and navigate in places. But I could see it being a useful during short term unrest or crisis even in populated areas. Thoughts?
