25¢ to receive a message is not something I'm willing to pay; it's something I literally have no way out of if I want a cell phone and don't want to cough up even more for unlimited SMS. AFAIK there's no way to just turn off SMS entirely, which I'd be more than happy to do as I've completely replaced it with various data-based services that I'm also paying for in my monthly bill (email, IM, iMessage, google voice, etc.) Even if I am able to disable SMS completely (without screwing up the parts of my plan that I actually like, at least), it's problematic because of the handful of people that do text me, they'd have no way of knowing that I never got the message (unless the telco would automatically respond on my behalf saying that number can't receive texts; I doubt this is the case). Some SMS-based services don't work with Google Voice and MMS is completely unsupported by it, and there's absolutely no fallback let alone a graceful one.
