Q: How to make my iPhone support FaceTime as I bought the phone from Saudi Arabia please advise

Phones sold in that area have Facetime permanently disabled on the device. There is nothing that you can do about it.

You can never have it on that iphone.

The government does not allow it there.

Well, you purchased in the wrong country if you wanted FaceTime...FaceTime is banned there, & permanently removed...that means no way to add it back.

You can do all of the software updates you want, it will not activate Facetime. It has been permanently disabled in the hardware. There is nothing that you can do to that device to make Facetime work. Period.

Apple will not change it and the discussion of jailbreaking is not allowed on the forum. Facetime is disabled due to government regulations. Devices sold there have to have it permanently disabled.
