iPhone 4 users have reported three distinct FaceTime issues:
1. No FaceTime option appears in the Settings app. In other words, you do not have the option to turn FaceTime on or off, and no functionality appears in the phone app.
First, try this process:
- Navigate to Settings > General >Restrictions and select “Enable Restrictions”
- Set the FaceTime restriction to on
- Select “Disable Restrictions”
- Go to Settings > Phone, and you should now see a FaceTime option, which you can turn on.
Failing the above, restore your iPhone 4 as a new phone. This will delete contacts and other data, but may resolve this issue. To do so, connect your iPhone or iPod touch to your computer, click “Restore” in iTunes, then choose “setup as new phone.”
2. FaceTime button missing from phone calls. In this case, the FaceTime option exists in Settings, but you cannot initiate FaceTime sessions from the phone app or from the contact screen. You may see a hold button instead of a FaceTime button.
Make sure FaceTime is on. Go to Settings > Phone and make sure that FaceTime is turned on. If you don’t see a FaceTime option, follow the procedures above.
Reset all settings. Navigate to Settings > General > Reset > Reset All Settings. This will erase stored messages, passwords and other information, but may resolve this problem.
Failing the above, restore your iPhone 4 as a new phone as described above.
3. FaceTime doesn’t work on some Wi-Fi networks due to firewall restrictions.
We noted a fix for this issue here, which Apple subsequently noted in a knowledge base document.
