With T-mobile "unlimited" mobile broadband, you have 1GB fair use limit, if you go over, you will not be able to download files or videos between 4pm-11:59pm. No extra charge.
T-mobile mobile broadband is the, so-call, best mobile data network in UK.
Update: 2GB of data was used up in 3 weeks, by 3 people with laptops (excluding me).
