Can I use FaceTime over cellular data?
Some wireless providers are limiting FaceTime over cellular calling to subscribers with specific data plans. Although iOS 6 provides for FaceTime over cellular, how can you tell if your iPhone has this capability?
To determine whether or not you have access to FaceTime over cellular, or you are limited to only making video calls over Wi-Fi:
On your iOS device navigate to Settings -> FaceTime -> Use Cellular Data -> ONOn newer versions of iOS the toggle is located here:
Settings -> Cellular -> FaceTime -> ON
If nothing happens, you should be ready to make and receive FaceTime calls over your cellular data connection.
