If a large enough percentage was paying the fee yes they can make it up but 10% I think you're off by a factor of 2-4, perhaps 10 when you consider the larger market they're trying to move to data plans to begin with. When the minority is sufficiently small, the pennies you move the profit maximizing point by aren't enough to justify the groan factor you have to deal with, hence I doubt the rate changes. We'll see I guess.
