There is no FaceTime application to launch on the iPhone series. Either from Phone or Contacts you can show the list of contacts. Click on one of those contacts. Then click on FaceTime.
The originating location of the iDevice is what determines what it is capable of doing. From what I understand, since your iPhone originated from the UAE, it won't be able to use Facetime... regardless of where you're using it.
