another internet and cell phone question

Streaming movies without a large data plan in a reliable service area will be frustrating. I don't watch a lot of movies but can tell you that internet on the road is a LOT different than high speed internet in a sticks and bricks home.

If you are planning to stay in one place for a couple months or more, just change your shipping address with Netflix to the campground and keep your billing address the same as your credit card billing address.
