I have the old Iridium / Motorola 9500 series which is bulkier and doesn't look as good as the newers versions but works fine... pretty well everytime I turn it on to use. On occassion it might be slow but does always work. It's worked for me in AK, northern Canada, Spain, MX, Russia and a bunch of other places that was cheaper than paying roaming fees on my cell phone. I also have a few of the older Globalstars and if you do feel yourself inclined to purchase one of those pieces of junk, give me your best price and I'll beat it by $50.00 bucks. They are garbage, but they do hold down the paper at the end of the desk just fine. There are also external antenas that allow you to sit inside a building and make calls. I also find that a window facing a certain direction usually works OK but might cut out. Make sure you get the wall plug charger as well as the car charger and it is nice to have an extra battery. There are tons of companies offering rental / purchase & usage programs. Let us know what you end up with. I think mine is called "Nortern Lites" package or something like that but I expect you will just get a phone with lots of minutes and have to pay for what you use. I'm sure we all are curious as to what you end up paying. Have fun.
