Hello alcody76,
Thank you for reaching out to Apple Support Communities.
These details may help.
You might have issues using FaceTime for one of these reasons:
- FaceTime and FaceTime audio calling might not be available for all countries, regions, or carriers.
- FaceTime isn't available or might not appear on devices purchased in Saudi Arabia, Pakistan, and United Arab Emirates, including Dubai. However, with iOS 11.3 or later, FaceTime is available on iPhone, iPad, and iPod touch in Saudi Arabia. And with iOS 12.4 or later, FaceTime is available on iPhone, iPad, and iPod touch in Pakistan. Update your device to get FaceTime in Saudi Arabia and Pakistan.
- Call forwarding isn't available with FaceTime.
- You try to switch from a FaceTime call to a phone call or a FaceTime audio call. To do this, end the current call and then make a new call.
- Make sure there isn't a FaceTime outage.
More details can be found here: If you can't make a FaceTime call on your iPhone, iPad, or iPod touch
If the issue persists, can you provide a few more details? When was the last time FaceTime worked on this device? What is the exact iPadOS version? Also, are any other devices expending this issue?
Cheers!
