After you've tried to change your Country or Location to find App or iTunes store still requires a form
of payment (although other locations may instead show an option for None) you may choose to
inquire of local or regionally accepted pre-paid iTunes cards such as the Apple pre-paid Gift card.
The Apple Support article and information concerning this topic changes by country and region.
The information for Saudi Arabia is visible in English from link below; wording is different than
the one previously posted that was intended to help those persons in India with the question...
in the bottom of these articles, is a link to locate other countries or regions for local information:
This is the correct link to Saudi Arabia for the topic answer. This should also allow regional contact:
• Why can’t I select None when I edit my Apple ID payment information? - Apple Support- Saudi Arabia
• iTunes - Apple Support - Saudi Arabia:
https://www.apple.com/sa/support/itunes/
Hopefully this may be of help to resolve this kind of issue where the terms or local conditions vary.
Good luck! 🙂
