I was "grandfathered" in with my provider having been with them for 20 years. My plan had slow speeds but unlimited data, but keep in mind that was before streaming.
Five years ago I wanted to change my plan to accommodate better download speed for streaming, but in doing so I would be limited to 50 GB monthly with a very high per GB surcharge over that figure. I did it anyway but had to watch my usage.
Shortly after changing the plan & if I remember correctly there arose some legal issues with internet providers limiting & gouging customers over GB home usage.
I still have the same plan but now have 300 GB per month. I was told by my provider that I would get a friendly email notification & warning if I ever exceeded the 300 GB but would not be charged for extra GB for first occurrence.
On another note what internet providers don't tell you is your speeds will become adversely affected by the more people using that provider in your service area.
My current plan @ $59 monthly is "up to" 50 Mbps download speed and "up to" 3 Mbps upload. They now offer 75/5 & 100/10 home usage plans also.
I just tried "pianotuna" test & got ping @ 36ms, download @ 52.28 & upload @ 3.24....... I must be the only one in my area using the internet right now.
I'm an expert in only one field....I believe it's somewhere in Kansas.
