The US.

Tethered traffic is usually routed differently. Almost all cellular data traffic is CGNATed or proxied, and different priority is assigned to different types of traffic.

For 95% of users, there’s no problem at all. When people push the limits, they find themselves in a pickle. I’m familiar with an organization with >50k devices across 4 major carriers 4-5 years ago. They probably had <500 people who required some sort of exception, ranging from a different plan to a more appropriate device and plan, to someone doing something crazy.
