My family and I are renting a RV this summer and heading to Yellowstone for about 10 days. The campground website specifically states that cell service and wifi is non-existent with the nearest internet service a 30 minute drive away. While I understand the point in unplugging, based on past experiences, either my wife or I will have to respond to at least 1 email over a 10 day period. I've looked at Iridium, but it appears to only work with their apps, so not a lot of options. Are there other options out there that others are using?
