Hey @Luluthelilly
Thanks for reaching out here in the Community!
Please be advised that Saudi Arabia is not an officially supported region for Roku which is why you are unable to access some channels.
Any Roku Player or TV can be activated to any Roku account, however, channel availability/access will vary from region to region. Channels that are currently available in any given region are certified for the Roku devices sold in that region.
For more information, you'd want to contact any specific channel/service provider to inquire further about which Roku devices they support their channel (app) on in your current region.
We appreciate your understanding.
All the best,
Kariza
