What do you guys use for communication in your truck camper?

For our older age and health reasons and the fact that most of our camping is out of cell range, we have a Globalstar satellite phone - got a promotion last year (still available) - unlimited minutes (voice and text) for about $900 with a free phone.This year we got a plan for 1800 minutes that wasn't as good a deal but didn't spend a lot on eating out this year!
