I live in a low-signal area and get 20-30 Mbps. However, I've had co-workers and customers claim up to 70Mbps depending on the situation. (This was before XLTE.) As with any internet connection, It's partially what you have, and partially the server you're connecting to. (Also keep in mind that many cellular devices will connect through a local ISP, such as a DSL provider at some point, so whatever they get can influence what you get.)
