Why don't cell phone companies block anonymous calls?

I was looking to see what my provider (AT&T Wireless) had as far as whitelist and blacklisting capabilities. Asides from putting an additional fee on that service, apparently they do not block anonymous calls at all. Nor does Verizon, who also charge for the whitelist/blacklist services (so for those apathetic about the T-Mobile merger and the lack of competition, just look at that as an example). I know these are services that land-lines offer, and it's not exactly a conceptually or technically difficult thing to do. So why don't wireless providers just do this?
