Mobilicity is doing what the little guys often do best -- undercutting its bigger rivals -- and it's doing that in an especially dramatic way this holiday season with a pair of pretty enticing new plans. The "exclusive holiday offers" include CAD $30 and $40 price levels ($30 to $40 US, coincidentally) that include unlimited calling and messaging, while the $40 option throws in unlimited US long distance, global text messaging, and unlimited data. That's not quite as spectacular now that the Canadian and American dollars are at parity -- but even so, it's definitely on the very highest rungs of the value spectrum. Interested? The plans are available through December 24th.
