Mobile operators are good at providing coverage maps with lots of bright colors that show extensive coverage across the U.S. In their advertising, they usually flash the maps up for a few seconds, giving the impression that wherever you go, you will have cell service. And even if you do not have LTE, surely you will have 3G or even good old 2G?
Well, no. Not really. This summer, we took a flying-driving vacation to Seattle and then drove through Washington, Idaho, Montana and Wyoming. We visited Yellowstone National Park (well worth the trip) and Grand Teton National Park (very well worth the trip!).
