Vita can receive SMS?

According to IGN, it looks like the Vita can receive text messages, but is missing the ability to send them out.  As you can see from this screen, a phone number has been assigned to the system.  Calling it will do nothing, but sending a text will have it pop up under “Notices from Operator”.  Will this be a feature Sony plans to expand on?  Wouldn’t it be nice to send a text to you friend when you’re looking for an opponent to play with?
