FaceTime is not just for video chatting. If your current smartphone plan offers only limited cellular minutes, consider using FaceTime Audio (FaceTime without the faces!) when calling other iPhone or iPad users.
To initiate a FaceTime Audio call, open Contacts, tap the name of the person you are calling, and tap the phone icon next to FaceTime instead of the video icon (which will launch a FaceTime Video call.)
Talk as long as you like without worrying about minutes!
