Szut, we definitely want to make sure that you're able to take advantage of the Disney+ bundle included in your plan! Please tell us, are you signing in to My Verizon through the account owner or account manager's online account? Are you using the app or the desktop/mobile site?
That's great to hear, Szut. When you're logged in as the Account Owner, you are able to see all of the lines on your account and not just details for your number. Accordingly, you'd sign up for the Disney+ Bundle as shown here: https://www.verizon.com/support/disney-bundle-faqs/#sign-up. Only one of your numbers need to be on a Play More or Get More Unlimited 5G plan (that were released in August of this year) that qualifies for the bundle in order to see the Disney+ bundle in your Add-ons. If you do not see the bundle listed in your Add-ons, then the aforementioned qualifying unlimited plans are not active on any of your lines. https://www.verizonwireless.com/plans/
