It depends on what type of subscription you currently have. If your existing Disney+ subscription is through:
Verizon:
You are not eligible for this offer. You can only have 1 Disney+ subscription on any Verizon account.
A third party
If your subscription is with a third party like Apple, Google, Roku, or others, this promotional offer will not automatically replace that subscription. After you enroll and complete setting up your account to redeem this Verizon offer, you will receive an email from Disney with information on how to manage your other subscription. You will continue to be billed for your existing subscription until you follow the instructions in that email.
Learn how to manage third-party subscriptions in the Disney Help Center.
Disney+ Premium (No Ads)
If you have an existing annual or multi-year Disney+ subscription billed by Disney, your existing subscription will be paused and will resume when the promotional period ends, when you opt out of the promotional offer, or if you cancel your qualifying plan or service.
If you have an existing monthly Disney+ subscription billed by Disney, your existing Disney+ subscription will be paused and will resume through Disney when your Verizon subscription ends.
To have your subscription paused, you must use the same email when activating your Verizon subscription that you used to purchase your original Disney+ subscription.
