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; 22.214.171.124 and 126.96.36.199 (Google’s Public DNS).
