Apple Watch Ultra 3 vs Garmin Fenix 8 Pro: Satellite SOS Tested

Apple Watch Ultra 3 vs Garmin Fenix 8 Pro, which smartwatch does satellite messaging better out on the trail? Gear I'm Using Now:* More Hiking Content* I tested the Apple Watch Ultra 3 and Garmin Fenix 8 Pro side by side on real hikes to see which one handles satellite messaging better when you're completely off the grid. Both watches can now send and receive messages without a phone or cell signal, but they work differently. The Apple Watch only switches to satellite when both your iPhone and watch are offline. If your phone connects to something like T-Mobile's Starlink network, that counts as online and the watch won't use satellite. The Garmin operates independently and doesn't rely on a phone at all. I compare coverage areas, ease of use, message delivery times, and whether these features are worth the cost over a dedicated device like an inReach. 00:00 Connection Limitations 01:37 How Connecting Works 05:52 Satellite Features 09:35 Reliability 11:20 Battery Drain 11:57 Cost & Coverage 13:38 Recommendations Disclaimer:*
