That's interesting because according to
p.2 of this document Dutch Vodafone customers are charged higher rates when roaming on AT&T than on other US networks. Hence you should assume that Vodafone NL's wholesale purchase price for airtime on AT&T is higher and so other roaming networks should be preferred. But there are many possible reasons why toggle does not roam on T-Mobile - one of them could be lacking support of the required CAMEL phase that enables realtime billing, a basic requirement for prepaid tariffs.
Anyway, I expect toggle to start assigning American IMSIs from Lycamobile sooner or later and then customers will be locked to T-Mobile.
