Hello,
Thank you for posting to the Apple Support Communities.
- You can view a list of regions where the Apple App and Media Stores are available by clicking the following link: Availability of Apple Media Services - Apple Support
I belive Iran is not in the list of countries where Apple provides service. In that case you must have your account set to a different country, in which case trying to use a service from Iran may fall under this restriction: Legal - Apple Media Services - Apple
- "Our Services are available for your use in your country of residence (“Home Country”).
And: "Certain Services and Content available to you in your Home Country may not be available to you when traveling outside of your Home Country."
- If you’d like to see more features added for a specific region, please submit feedback to Apple directly here: Product Feedback - Apple
