Other option you can consider is Starlink mini. All you need is 12Vdc to power it. Setup a wifi connection and then use wifi calling on your cell phone to call out. You have everything (phone, texting, internet, etc). Works just about anywhere.
Aberfoyle has some 26 ZR600EPS that were corp demos for $16 and change with a 2 yr warranty. That didnt seem like a terrible deal for a sled that is considered new by the factory
