GoSmart is the MVNO that T-Mobile has been playing with. If this endangers the $30/mo plan that everyone hails as the savior of America, well, T-Mobile will have a large base of very vocal and angry customers.
There’s no official word on nationwide pricing, but GoSmart currently features three monthly service tiers: a $30 plan with unlimited voice and text messaging, a $35 plan with the same plus unlimited web browsing, and a $45 plan with unlimited voice, text, and up to 5GB of 3G data.
