Hi Lokidiscool,
Thanks for reaching out in Apple Support Communities. I understand that you're having trouble with the FaceTime connection on your iPhone and when you tested on your Mac you encountered similar behavior. I know how important it is to connect with friends and family using FaceTime on your devices; I'd like to help. Since you mention this behavior is occurring on both your Mac and iPhone, it's possible there's an underlying issue with your Wi-Fi connection, even though you've restarted your modem or router. I'd suggest trying to make a FaceTime call using only a strong cellular connection to see if there's a difference, then take a look at the information below:
If none of the above reasons apply to you, and you still can't make or receive FaceTime calls, follow these steps:
- Make sure that your device has a Wi-Fi connection to the Internet or a cellular-data connection.
- Learn more if you're using router, firewall, or security software that restricts Internet access.
- 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.
- 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.
- Go to Settings > General > Date & Time and turn on Set Automatically.
- Restart your device.
- Update your device to the latest version of iOS.
If your cellular connection or Wi-Fi network are running slow, or other users are streaming 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're calling are using a fast Wi-Fi or cellular connection. If you’re using Wi-Fi, FaceTime requires a broadband connection."
If you can't make a FaceTime call on your iPhone, iPad, or iPod touch
One of these solutions might help:
- Quit FaceTime, then open FaceTime again.
- Restart your Mac (Apple menu > Restart).
- Make sure that FaceTime isn't open, then see if your camera works in another application, such as Photo Booth. If it doesn't, you know that the issue isn't related to FaceTime.
- If you have multiple cameras or microphones connected to your Mac, check the Video menu in the FaceTime menu bar to make sure that you have the correct camera and microphone selected.
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:
- 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."
If FaceTime isn't working on your Mac
It's also possible there is a connection issue on your friends side since you're able to see and hear them without issue; I'd suggest having them test using cellular only and reset their wireless connections as well.
Best Regards.
