A:AnswerYes. There are two package options. The unlimited and 50gb. I suggest trying the unlimited first to see how much you actually use because I was surprised at my overall usage.
A:AnswerIt depends on if anything is in the way and how many walls the signal would have to carry through. I have gotten signal that far away from our router. However, I wouldn't expect it to be strong or consistent at that distance. You probably need an extender, repeater, or to just run outdoor cable to the cabin(most reliable).
