Welcome, @BillieDawn514!
We're grateful to have you here in the Roku Community!
Thanks for reaching out. In addition to what our Community Guru provided in the above post, here is the list of Roku-supported locations. Also, The Roku Channel is available on your Samsung TV. You may search and install it directly.
Furthermore, we highly recommend enhancing your Samsung TV experience by connecting a Roku streaming device. This setup will allow you to access a wide selection of free movies, popular shows, and applications that cater to various interests.
Feel free to respond if you need further assistance or clarification. Happy Streaming!
Best regards,
Carly
