I've been using an Iridium sat phone for a few years now. Sorry I don't know the model off hand - I have it down on the boat. I use it in SE Alaska and have used it between Vancouver BC and Alaska. It works very well in our crusing area. It makes everyone sound a little drunk, even the voice mail lady, but other than that, no complaints. Sometimes you have to be outside, but I have found I can use it successfully on my flybridge, which has a canvas cover. My employer pays the fees, which start at about $40 per month, and goes up from there, depending on usage. I don't use it for data (Internet) or anything else, just voice.
I used Globalstar before this and it was horrible.
