"Being on the internet" is not part of my job, and many nights I don't bother to take the laptop out of its bag.
I never use wifi because I'm paranoid.
While driving I listen to podcasts or streaming. I never predownload anything.
I don't know if I ever get throttled. Sometimes, even in this day and age, I'm out of cell range, and my podcasts pause.
I might watch a movie on the phone once a week or so.
Which is not at all helpful to you, except possibly to observe: the less you need, the better it is.
Your lifestyle and work may just be five or ten years ahead of it being worthwhile for businesses to provide what you need.
