Satellite phone operate on different satellites, depending on where it was purchased and which satellite it is tuned to. You can have the satellite changed to cover everywhere as you travel, but NO, there is NO satellite that covers all of North America. There are some that are close to full coverage in the lower 48, but again, none provide 100% coverage. Contact your local provider for info on what they have to offer. I do know the price has come WAY down on them. We paid under $100 for ours and the minutes are now much cheaper than they used to be.
