Hi @Ori888,
Thanks for your first post in the Roku Community!
Please be advised that Israel is not an officially supported region for Roku, which is why you are unable to add Disney Plus.
Any Roku Player or TV can be activated for any Roku account. However, channel availability and access will vary from region to region. Channels available in any region are certified for the Roku devices sold there.
The channel is managed and developed by its channel publisher. We suggest you contact them to let them know you want their streams on Roku Israel.
We appreciate your patience and understanding.
Best regards,
Chel
