I was going to do that also but the cs rep on the phone says im only paying $29.99 for mobile hotspot and unlimited data so i decided to leave it on
Another poster said he deleted hotspot via immediately after activating that it left unlimited data on his account. I'd rather learn sooner rather than later if it's going to leave me unlimited, as (1) i'm not interested in paying $30 for hotspot, and (2) I want to be able to get my 4gb back sooner rather than later if they remove my unlimited. So we'll see.
