Do you have a very small, limited number of minutes on your cell plan, but typically are on a wifi connection and avoid using your cellular data? If this sounds like you, then you need to learn how to place a FaceTime audio call. Quite simply, it is a phone call that uses data instead of your cell minutes, and if your wifi is free, then it doesn’t cost you anything at all!
To place a FaceTime audio call, you can do so straight from your friend’s Contacts entry. Assuming that they have an Apple ID setup and associated with the email address you have saved for them (correct me if I’m wrong on this point), you will find FaceTime listed beneath their phone numbers. Next to the word FaceTime, you will find two icons: one of a video camera and the other of a phone handset. Obviously, if you would like to have a traditional FaceTime video call, then you can tap on the video icon to start it. However, if you’d like to take advantage of the free calling that comes with FaceTime audio, then you simply have to tap on the phone icon. It will immediately start dialling your friend, and will note on the screen that it is a FaceTime audio call. When you’re done your call, you hang up as normal.
Using this trick is a great way to save your limited cellular minutes for those times when you really need them! You can still do this over your cellular data connection, though with free wifi so commonly available, you can basically place your audio calls for free!
