I was holding back from buying the Garmin device so I could know what apple offers. It’s much inferior to garmin. Garmin uses a much better iridium network that has greater coverage and doesn’t require you to point the sky certain angle. It also allows you to message anyone in the world and receive text message from anyone. It’s more expensive but if those features are important , then you have the choice. With apple you can text ur friend socially in the middle of desert or ocean.Garmin has similar device for many years now. So you can simply do a google search and see how people have been dealing with it. Or go to REI I’m sure they can tell you a thing or two.
