No doubt a response to Virgin Mobile’s serious push to reign supreme in the pre-paid market, T-Mobile today announced two new unlimited pre-paid plans which go live this Wednesday. Under the new plans, $15 will net users unlimited text, picture and video messages with nationwide voice calls at 10¢ per minute, while $50 offers the same in terms of messaging but allows for unlimited nationwide calls with no per-minute fees. Definitely not bad plans if you’re looking to kill off a landline and not get locked into a lengthy contract commitment, but we’d have loved it if T-Mobile were to introduce a third plan with data. We mean, they are trying to play it both ways, right?
