I don't have one, but if I got something like that, I think I'd get a satphone instead. Not cheaper, not lighter, but more versatile. They are getting smaller and lighter than they used to be, but the price is the big barrier for most people. the main reason I don't have one. But, you can rent them and that is feasible even for trips of a few weeks.
