can i download facetime if i dont have in the device

Find a missing FaceTime app - Apple Support

FaceTime for OS X

https://itunes.apple.com/us/app/facetime/id414307850?mt=12

On the device, open Settings, General, and then About. If the model number has AB, AE, or possibly AH just before the slash, it won't have FaceTime in the United Arab Emirates, Saudi Arabia, or any country outside the Middle East; only SIM cards for certain Middle Eastern carriers enable it. Otherwise, check the device’s restrictions.
