Often in the US too and unlimited usually doesn't mean unlimited at full speed... For example, if you use your internet at full speed for a full day, you probably would get throttled for the rest of the month.
That's crazy. Unlimited here is uncapped speeds with a soft fair use download ceiling of 1TB a month (last I checked, which is quite a while ago). If you surpass that repeatedly you're asked to tone it down, and if you continue to download that much, you'll have to pay more for a higher cap.
