That's for sellers, but not users. What I'm trying to figure out is if I just put this directly on my router and 2 cell phones if there is any decrease in speed. I'm assuming yes at some point but don't know how much testing you've done. Or if you're implying that it solely depends on the provider you're using and how many other users they have at that given moment. Idk how bandwidth is managed if say a seller has 10 clients and each of those have 5 devices running at the same time.
