Virgin Mobile has always positioned itself as a super-crazy-value carrier in the US, and that trend certainly continues with its latest plan option, "Totally Unlimited". The idea's about as simple as the name implies -- the MVNO hooks you up with unlimited calling at any time of day or night for a shade under $80 a month, which already positions it favorably against all the nationals and major regionals -- but the coup de grace has to be the contract-free nature of the whole thing. When you sign up, Virgin doesn't want your soul for two years, and it doesn't even want your credit card if you'd prefer to pay your dues with a crumpled-up wad of cash every month (where you got that money is none of our business, after all). Unlimited text and pixture messaging can be added for another $10 monthly, which ends up pitting Virgin squarely against the $89.99 plan offered by one of its corporate parents, Sprint (which doesn't actually own much of Virgin Mobile anymore, so we guess there's probably not too much love lost there). Look for Totally Unlimited to hit the streets on July 1.
