Greetings @Sasitharan
Welcome to the Roku Community and thanks for posting regarding your inquiry of channel availability.
Please be aware that channel availability/access on Roku devices will vary from region to region. 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/service provider to inquire further about whether they offer their channel/service on the Roku platform in your region.
If you have another inquiry in the future, please don't hesitate posting in the Roku Community again.
Thanks,
Danny
