I've been using these exact products for four years. We go to the Bahamas in November and come back in June. I use an Iridium satphone. It is great...no problems...fast...easy. I don't worry about propogation, etc. It has always worked...wherever. Actually, Chris Parker gets his WX data (gribs) from Ocens. I always get the WX first thing every morning...then decisions are made.

I couldn't say more about how well this system works. You have the added benefit of voice capability as well as SMS text.
