Didn't know I would be needing it until I needed it. My phone has unlimited nontetherable data and on paper I had data at this spot. I also had coverage on my work, but the person didn't want to touch this issue because it was complicated.

My point is that that these devices have a purpose as a fallback/filler when you don't hit the ground knowing you'll need the data, as a bridge until you can get things setup, or when you've got very short stops in places.

All my other stops in Australia had great wifi. I actually only needed it that one day.
