The technical and true to tmobile term and conditions answer...
To use your phone as a mobile hotspot, would require a tethering plan at cost of $14.95 (last I checked).
My from experience answer, I've had no issue of using my phone as a hotspot... and they can't charge you unless you are willing to enter into the tethering program only prevent you from doing it.
Does not appear there is any additional fee. But I'm sure if it's used too much that T-Mobile would contact you about it.
This thread on XDA has some tips if you run into issues.
Interesting (in a good way) how they kept the tethering options open.
