Hi @LEE_JE_MYUNG
Thank you for the inquiry!
Channel availability or access on Roku devices will vary from region to region due to service limitations or geo-restrictions. A Roku device will work in any location. However, channels may not be available on your device in that location, based on each channel provider's discretion. For more information, you'd want to contact any specific channel or service provider to inquire further about whether they offer their channel or service on the Roku platform in your region.
We hope it helps!
Warm regards,
Lianna
