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?
