At the end of the day, its Deutsch Telcom one way or the other.

The roaming charges are partially correct, there is signaling data and potentially voice going to/from overseas even if you call UK-UK with your US mobile while in UK so from the technical standpoint it's not just accounting betweek T-Mobile UK and T-Mobile US. That they could make a profit for a fraction of the price is another discussion.
In any case I don't see THIS making any dent in their bottom line. It might help without your personal bill a bit but a juggernaut like T-Mobile won't care about UM and the like which we have to admit are little more than "apartment companies". And to make things worse UM isn't a good long-term solution for any given place with all the incoming fees/expensive numbers. So you won't be really able to use the UM number as your main number and in effect any UM-based solution would have the added disadvantage of lost convenience.
