Solavei starts carrying nano-SIMs for iPhone 5 nomads
 

Those who want to use an unlocked iPhone 5 in the US beyond AT&T have had relatively few places to go for an exodus, T-Mobile and Straight Talk usually being the two carriers on the short list. It's time to add a third: Solavei is now carrying nano-SIMs for its T-Mobile-based virtual network. There's not much mystery to what's involved after that, since you're still getting the singular, all-unlimited $49 plan and no guarantee of 3G when even T-Mobile's own spectrum refarming is still young. If you can live with those potential caveats for the sake of network and contract independence, Solavei is waiting.
