Phone: 'You're in satellite mode. You can send text messages, including to 911. Emergency calls may still connect if a mobile network is available near you.'
Emergency SOS: 'If you call emergency services when you're out of range or not connected to a mobile network, we'll connect you via satellite so you can send an emergency text.'
Samsung Messages: 'Samsung Messages doesn't support satellite messaging. To send and receive texts via satellite, you need to make Google Messages your default messaging app.'
The biggest takeaway is the part about sending messages including to 911, meaning this won't be limited to emergency texting. From Samsung's wording, this seems to be regular text messaging.
