Cell Towers have no place in National Parks/Forests and other nature preserves. If you're in the middle of the ocean you're not going to have cell phone service either, and you should plan accordingly.
Do roads have place in national parks? If so then cell towers also.
I mean if I see asphalt then it is quite reasonable to expect also cell service.
I was i national parks in Europe and I always got cell service. I might be lucky (considering the article and posts about Germany) but in US I was in one park (actually two, but I don't remember situation with mobiles in one) and I did get cell service even before the gates.
I don't expect to have cell service if the park doesn't have roads, just hiking tracks.
