You can get anything you want with expensive business packages, including unlimited data. I use a wifi hotspot using an unlimited and fast LTE connection whenever I business travel (not sure what they pay for it, I think we even have boxes that pool multiple providers but personally I never used them). Telekom even publically advertises an unlimited LTE plan nowadays (but that is 200€ a month). However, the typical consumer plans are pretty limited.
