Hi Macbloom,
Thanks for coming to Apple Support Communities for help today.
It sounds like you are talking about Emergency SOS. You can read all about how the feature works here: Use Emergency SOS via satellite on your iPhone 14
You can try the demo, but the feature isn't meant to be used outside of emergency situations.
"Try the Emergency SOS via satellite demo
To learn how Emergency SOS via satellite works, try the demo. You need to be outside, on relatively open terrain, with a clear view of the sky. Trees with light foliage might slow down the connection and dense foliage might block it. Hills or mountains, canyons, and tall structures can also block the connection.
If you don't have Location Services turned on for Satellite Connection, you're prompted to turn them on before you start the demo.
- Open the Settings app.
- Tap Emergency SOS.
- Under Emergency SOS via satellite, tap Try Demo, then follow the onscreen instructions.
To use the demo, you need to be in a country or region where Emergency SOS via satellite is available. The demo does not call emergency services."
Have a fantastic day!
