Can you text and call on an iPod touch ?

My sisters boyfriend is getting an iPod touch he wants to know if he can call and text her on it he doesn't have WIFI at his house. He can't afford a cell phone also his mom won't let him have one because he spends so much time talking to her on the home phone. Is there a way he can text and call her on... show more My sisters boyfriend is getting an iPod touch he wants to know if he can call and text her on it he doesn't have WIFI at his house.
