How can I find FaceTime app in my UAE bought iPhone se to use in India
I Bought an iPhone se from UAE through souq.com
in add they shows that phone is with face time
iPhone SE, iOS 10
you will never find it.
iPhones from some countries have FaceTime permanently blocked / removed.
I know about UAE and Saudi Arabia, not sure about other countries from that region.
Anyways, if your phone doesn't have FaceTime, it will never have. Better sell it and buy one from your local authorized apple reseller.
