FaceTime, they can always see me but I can never see them.

Hello Rosebud1a,

We'd like to share steps that can help you further isolate and potentially resolve this behavior. Get started here: If you can't make or receive a FaceTime call on your iPhone or iPad - Apple Support

"If you still need help

If none of the above reasons apply to you, and you still can't make or receive FaceTime calls, follow these steps:

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.

1. Go to Settings > General > Date & Time and turn on Set Automatically.
2. Restart your device.
3. Update your device to the latest version of iOS or iPadOS."

Best regards.
