Thank you for contacting us regarding the Tennis Channel Plus. I was not able to locate any information about Tennis Channel Plus, only about The Tennis Channel (HD). We regularly examine our channel lineups and talk with a wide range of programmers to ensure that we are bringing the content that our customers want the most. We appreciate you reaching out.
Thanks for clarifying @billmich88888. I found some information. If you do have the Instant TV package, and if the Tennis Channel Plus is available in your area, it would require a subscription for the Sports and News channel add-on.
