two years ago here, they throttled at 7GB per day
that was back when Clear had 6mbps speeds all day long, rather than 8X slower now during non prime times -- Clearwire actually posted that bandwidth limit ahead of time, and it was for a 24 hr period that it turned into half speed, then you could be more careful the next day about not being a bandwidth hog.
Today it gets so slow between 4pm and 11pm that you couldn't begin to download 7GB unless there were twice as many hours in a day.
To their credit, they weren't accepting new customers on our tower for 3 weeks in September, but that was only after overselling our area by at least a factor of ten to begin with.
TERRIBLE, TERRIBLE, TERRIBLE what has happened to their service.
