Q: I don't have FaceTime in settings I have iPhone 6plus

Where did you purchase the phone? Which country? FaceTime is only available in certain regions.

1. Make sure your device supports FaceTime. FaceTime isn’t available or might not appear on devices purchased or used in Saudi Arabia, United Arab Emirates, and Pakistan.

2. Search for the FaceTime app in Spotlight.

3. In Settings > General > Restrictions, make sure that FaceTime and Camera are on. If your Camera restriction is on, you won’t be able to use FaceTime.

4. Update your device to the latest version of iOS.

If you still can’t find the FaceTime app, back up your device using iTunes or iCloud, then restore your device. After you restore the device, set it up by selecting your region and language. Then, restore the data using the iTunes or iCloud backup.
