Yep, you can't. Even though the carrier gives you a "number" SMS messages are usually blocked. The only "text" message you can get are iMessages that are sent to you via your iCloud ID.
Not SMS messages but you can use imessenger which is like using yahoo or msn messenger except up I can only send messages to iPhones iPod touches and other iPads for now. Hopping that they build a client for Mac OSX soon

JSYK, iMessages is currently available for download as a beta. I will say, though, that it has been less-than-great on Lion. Even on my iPad, sometimes iMessages won't all come in, and they only show up on my iPhone. It's a great concept, so I hope they work out all of their bugs soon.
