I already subscribe to the Paramount+ Essential plan through Paramount+. How do I upgrade to the Paramount+ with SHOWTIME plan?

If you are an existing Paramount+ Essential subscriber, you can upgrade to the Paramount+ with SHOWTIME plan. Please click here for instructions on how to switch your plan, depending on how you signed up for Paramount+.

If you also have an active SHOWTIME subscription, you should cancel your existing SHOWTIME streaming subscription to avoid being charged for multiple SHOWTIME subscriptions.
