I am sure some evil lawyer will make the case for you to be liable for ALL traffic that get passed over the mini cell that you are hosting. You aren't EE, O2, vodafone etc who have a phalanx of lawyers to help them.

And I'd expect that the bandwidth will come out out your ISP's quota. Oh, there are so many problems waiting to bit you financially.
anon for obvious reasons...
