Good point re: Dish being interested. They could ask for divestiture of Family Mobile and SIMple Mobile brands, since both use T-Mobile exclusively, and swapping them over would minimize the impact to those subscribers, while providing Dish an even larger customer base. I'm sure T-Mobile gives Dish a better deal than they do Tracfone, as not only does Dish have a larger subscriber base (Boost is larger than Tracfone's entire non-VZW customer base), but they negotiated their MVNO agreement when T-Mobile had to get the deal done to merge. Dish could push for divesting T-Mobile based customers from the other multi-carrier brands (Tracfone proper, Straight Talk, Net10, SafeLink), but splitting out the brands might be more trouble than it's worth at that point. Moving an entire brand over would be simpler, even if those brands are sitting on a unified backend on Tracfone's side. Dish will have a billing system of their own to migrate folks to anyway.
