All of my TVs have built in and are ROKU televisions, therefore do I have to pay a monthly fee to use them
Thanks for the inquiry.
There is no charge to use a Roku TV or a Roku device once they have been purchased. The only costs that are associated with your Roku TVs moving forward would be any subscriptions to channels or content purchases that you make.
