For it's the cheap cheap price of 22.4€/person for 20 GB 5G per person. And that's just because my father has been a customer for a long time and I'm a second device in his contract now, with 50% off. I also reach the 20 GB limit fairly often, especially when on the go a lot. Because Deutsche Bahn. F them. Not even a working Captive Portal is possible for them, so my Laptop has to connect to my Phones Hotspot. I'm in luck with coverage actually, it's pretty OK even in my village and all around. It's just bad in my school.

Not really, almost everyone has WiFi. However, many only have DSL - with speeds up to 10 Mbps or even lower. And that still for a price that's way too high. Usually it happens at more remote places, like 10 km away from the nearest city. Only one ISP is available, nobody cares about upgrading the rotting copper cables, or even laying fiber, so the customer just gets what's available for the price the ISP wants, there are basically no restrictions. We're very lucky to have Gigabit for 50€/month and soon fiber - and that's not even certain. A company is laying fiber, they're basically called 'German Fiber Optic'. As they only offer static public IPv4s for a premium price however, we didn't go for it. Rule of thumb is that either other ISPs will do their own cables just as the first one has been finished, so as not to lose customers. As ISP 1 that originally laid fiber could charge any amount for that only cable though, ISP 2 will either bite their cheeks and rent it or actually lay it themselves. From that point on the cable will be cheaper for ISP n>=3, as ISP 1+2 want to get them as a customer. So we just need to wait. Not an option for, as said, remote points, who may not have any acceptable connection but a tower right in their backyard.

Yea Illinois internet disparity is awful. ISP prices suck and it's usually either Comcast, AT&T, or no Internet.

Mobile coverage only gets better the closer you get to Chicago, but in the middle of Chicago it's hit or miss and there are random dead zones everywhere in the city.

Make sure the toilet is too tall for most people too.

A jammer would be the stupidest thing a place could do. Is is illegal and enforced, plus cell companies help investigate it. And Faraday cage is not necessarily illegal.
