"If you need help with your connection or call quality

A slow or busy Wi-Fi network might cause issues with your FaceTime call. If you experience connection alerts, or low-quality audio or video, or an exclamation point  over a video tile:

• Make sure that you and your recipient have a fast Wi-Fi or cellular connection. FaceTime calls over Wi-Fi require a broadband connection.
• Check for issues that might be slowing down your connection, such as someone streaming content over your network.
• If you have questions about your internet speed, contact your internet service provider."

We hope this helps.

Cheers!
