Several people have reported an issue in which making or receiving a FaceTime call fails on their iPad, iPhone and iPod Touch.
Fixes For When Your FaceTime Call Failed
- FaceTime is not available in every country
- Make sure FaceTime is enabled: Settings > FaceTime
- Ensure that camera and FaceTime are not disabled in Settings > General > Restrictions
- Make sure that both parties have an active Internet connection
- Try re-enabling FaceTime by tapping Settings > FaceTime and toggle off and on again
- If you’re trying to use FaceTime over cellular, make sure that Use Cellular Data is on for FaceTime. Go to Settings > Cellular > Use Cellular Data For, and turn on FaceTime
- Make sure time zone is set to your current zone OR better yet, have iOS set this automatically. Go to Settings > General > Date & Time and turn on Set Automatically
- Reset your network settings. Tap Settings > General > Reset > Reset Network Settings. This also resets WiFi passwords, cellular settings, and any VPN settings
If the problem persists:
Restart your iOS (iPad, iPhone and iPod Touch) device by pressing and holding the Sleep/Wake button for a few seconds, and then slide the slider. If restarting doesn’t fix it, it’s reported that changing your DNS settings fixes this issue: Settings > Wi-Fi > then select the blue arrow next to your current Wi-Fi network and then tap the “DNS” field and enter the DNS servers; 18.104.22.168 and 22.214.171.124 (Google’s Public DNS).
If that didn’t fix the issue, let’s reset your network settings–go to Settings > General > Reset > Reset Network Settings. Performing this action removes any stored WiFi passwords so have these available to add in again.
If no joy, let’s reset all settings. Go to Settings > General > Reset and tap Reset All Settings. Performing this changes all your personalized settings back to defaults including any accessibility settings, wallpapers, and stored WiFi passcodes. It does NOT erase any data like photos, messages, and other app data.
If none of this helps, you may need to backup and restore from a backup (or set up as new). OR, make an appointment at the Genius Bar of an Apple store to run Diagnostics on your device.
