two different plans on the same account?

user_pu8jog - Hello, and thank you for joining us on the Xfinity Forums! We really appreciate you reaching out with your question, it’s a great one. No extra steps are needed to remove your old plan when you make changes through your Xfinity account online. For example, once you log in and select a new plan, completing your order automatically activates the new plan and removes the old one. I hope this clears things up and makes the process easier for you! If you have any other questions or need help along the way, we’re here for you.
