FaceTime isn't working On iPhone?

Ok lil more info?
what carrier, iphone, firmware and what you tried

Are you calling over 3G? IPhones with iOS 5 or less can only use facetime over wi-fi. Hope this helps

Facetime works on only Wi-Fi for iOS 5.It will work on a mobile network in iOS 6. Make sure your iPhone is connected to Wi-Fi before using Facetime.

You don't say

  • Why isn't iOS 8.3 letting me FaceTime? Yesterday I updated the iPhone 4s with iOS 8.3, because I thought it might help my camera since all I seen was black but now the update worked but I can't FaceTime anyone. The app isn't even there
