Why FaceTime not working?
Why FaceTime is not working?
ACTIVATING FACETIME AND IMESSAGES
Activating Facetime and Imessages on your phone requires the ability to send SMS messages and depending upon where you are that might be an international SMS. Check with your carrier to see if your plan supports sending of international SMS messages. If you are having trouble activating Facetime or Imessages turn them both off on your device and reset the device (Hold down the Sleep/Wake button and the home button together until the apple logo appears (ignore the ON/OFF slider) then let both buttons go and wait for device to restart (no data will be lost)). Wait for the device to restart and wait a minute and turn Facetime and imessage back on and wait for activation. If that does not fix things read the following articles:

FACETIME MISSING
The governments in some middle eastern countries have banned Facetime and it is disabled on iphones purchased in those countries. The countries include KAS, UAE and others. There is no way to get Facetime on such phones (for example it cannot be downloaded and installed) and taking the phone to another country does not cause Facetime to reappear on such phones. In support.apple.com/kb/ts3367 it says “Note: FaceTime may not be available, or may become unavailable, on devices purchased or used in certain countries, including Saudi Arabia and the United Arab Emirates. Check your device's region of purchase for more information.”
