Having the 5G logo on your phone doesnt necessarily mean your phone is speaking 5G. It's...complicated. - Most US operators do not have ubiquitous 5G radio coverage, so, they do what is called 5G NSA where your traffic ultimately ends up veing processed by the 4G core infrastructure that they have. Which is already overloaded and a bit creaky. - Some operators can do real 5G, "5G SA", where the whole flow end to end…
I live in a rural area (not a single Starbucks in the county), and in 50% of the town, my phone has 5GUW coverage. I can download apps, playlists, and movies quickly. I recently downloaded UPBGE (430MB) on my iPhone in only a few minutes. This wasn’t possible on LTE and is worth the extra $10 for me.
The lack of a corporate coffee store does not necessarily mean it’s a rural area. Been to plenty of small population counties and there was at least one starcrack store in the area, including a McDiabetes, and other low cost crap.
Usually a rural area is defined upon the population size and density.
