Hey, Lisa here. I'm going to tell you how to make a FaceTime audio call on your iPhone. So just like you would with a normal call, first you're going to find the contact that you want to talk to. So you can tap on your phone, and then go to your contacts, and here I've pulled up the one that I'm going to call. So, when you look down you're going to see the name, then the phone number, and then you're going to see FaceTime.
To the right of the word FaceTime, you'll see a little video icon, which will be for a FaceTime video call, where you're going to see them in the video and they'll see you or you'll see an icon of just a phone. When you tap on that, it will take you to just an audio call. On here it will just use the FaceTime audio. So you're not actually using your minutes with your cellphone carrier, you're just using your data, so over WiFi or your cellular data plan. And there you go, that's how you make a FaceTime audio call.
