For the behavior you're seeing in FaceTime, check your network connection and have a look at this information:
If your cellular connection or Wi-Fi network runs slowly, or other users stream audio or video on the same Wi-Fi network, you might have these issues:
- Connection alerts or unable to connect
- Choppy video calls
- Black screen
- Dropped calls
Make sure that both you and the person that you call use a fast Wi-Fi or cellular connection. If you use Wi-Fi, FaceTime requires a broadband connection.
Also, give these additional steps a try:
1. Make sure that your device has a Wi-Fi connection to the internet or a cellular-data connection.
2. Learn more if you're using router, firewall, or security software that restricts internet access.
3. If you're trying to use FaceTime over cellular, make sure that Use Cellular Data is on for FaceTime. Go to Settings and tap Cellular or tap Mobile Data, then turn on FaceTime. If you're using an iPad, you might see Settings > Cellular Data.
4. Go to Settings > FaceTime and make sure that FaceTime is on.
- If you see "Waiting for Activation," turn FaceTime off and then on again. Learn what to do if you can't activate FaceTime.
- If you don't see the FaceTime setting, make sure that Camera and FaceTime aren't off in Settings > Screen Time > Content & Privacy Restrictions > Allowed Apps.
- Make sure that you have the correct phone number or email address listed.
5. Go to Settings > General > Date & Time and turn on Set Automatically.
6. Restart your device.
7. Update your device to the latest version of iOS or iPadOS.
