I do. I have a Garmin inReach, and it helps. But it takes ~5 minutes for one exchange of a text message. It's not enough to diagnose and fix a complex problem remotely.

Why not use a standard satellite phone instead? Rates are reasonable and in the $2/minute range. Your use case sounds like it's easy to justify that.

Iridium Certus is something that may be an option. Their new constellation just recently came online. I am uncertain of end device availability/support though.

I currently pay $25/mo for wired internet, 25Mbps & 1TB/mo cap, no discernible latency.

Closest available is $80/mo satellite internet, 12Mbps & 40GB/mo cap (overage => deprioritized), latency measured in seconds.

While little to go on, assuming Starlink will be aggressively competitive on all factors.

There's not as many as you think, and they all blow. Not enough bandwidth, way too much latency, and very very expensive.
