After reviewing your post, it sounds like you want to know about Apple services functioning in Saudi Arabi. One example would be FaceTime, in this example, FaceTime would not work in Saudi Arabia.
You might have issues using FaceTime for one of these reasons:
- FaceTime and FaceTime audio calling might not be available for all countries, regions, or carriers.
- FaceTime isn't available or might not appear on devices purchased in Saudi Arabia, Pakistan, and United Arab Emirates, including Dubai.
- Call forwarding isn't available with FaceTime.
- If you try to switch from a FaceTime call to a phone call or a FaceTime audio call.
Thank you for using Apple Support Communities. Have a nice day.
