there are plenty of past events that would question your knee jerk "good call." Remember that Dan Borislow's big time long distance reseller in the 1980s and early 1990s was an AT&T reseller. Also, when MJ first introduced international calling capability, he splashed the AT&T name all over his websites. Dan is a very proud guy, and having that link to AT&T would increase the credibility of his offer as well as make it available to more subscribers. It might ultimately be T-Mobile, but AFAIC it's not so obvious.
