Check out satellite radios, they operate anywhere.
not really. most work very poorly inside buildings, cars, etc.
And those who use GEOS sat's need a clear view of the southern sky for reception........ Like aiming a TV sat dish.
Irridium based systems that don't use geos sats are much better but can suffer reception problems for about 10 minutes every hour depending on terrain.
Now if you want to send/recieve text messages the Garmin inreach which uses Iridium sat's. works quite well. Seldom has taken more than a few minutes to lock onto a sat and send a message when I am outside. Inside a building, even a trailer/house much more problematic.
Spot uses GEOS sat's and only allows one way communication, send only, no recieve.
Sat phones can be rented for short term use.
