Yes, it just popped up as a notification.
Is this something we'd have to pay for if needed or would it be part of our plans with our carriers? And is its availability carrier-specific?
[Edit] Here's what a search with Grok came back with:
"Yeah, that notification's legit—the Galaxy S26 Ultra has built-in satellite texting, and Google Messages is one of the apps that can tap into it when you're out of cell range. It's not carrier-specific in the sense that the phone hardware supports it globally, but whether you actually get to use it—and how—totally depends on your carrier.
Right now in the US, it's rolling out mainly through Verizon and T-Mobile. Verizon keeps it free for basic texting and SOS—like, no extra charge, just works if you're on their plan. T-Mobile's a bit mixed: emergency stuff's often free (even for non-customers if you register), but fuller texting or data might hit you with about fifteen bucks a month on some plans—though they've been making more of it free lately.
It's not something you pay per message; it's usually bundled into your carrier service or a small add-on. And yeah, it's satellite-specific—uses Starlink or Skylo networks directly from your phone, no tower needed, just clear sky view. Super handy for hikes or remote spots, but texts are short and slow compared to normal.
If you're on AT&T or someone else, it's coming soon, but not there yet. Check your carrier app or settings under "Satellite" or "Emergency" to see what's active—should tell you if it's free or not. Cool feature, right?"
