How to get free Disney+ from Verizon
If you have (or sign up for) a Verizon unlimited data plan
If you already have a Verizon unlimited data plan, all you need to do is launch the My Verizon app, tap the menu icon, hit Account, and sign in. From there, tap "Add-ons," hit the Entertainment tab, scroll to Disney+, and tap "Enroll." Once you accept the terms and conditions, you'll be shown a Disney+ enrollment screen and eventually be taken to the Disney+ login page to set up your account. From there, you just need to download the Disney+ on your phone, log in, and boom -- you're done. If you don't have the My Verizon app, you can also do all of this from your account page on a desktop.
To upgrade to an unlimited plan, launch the My Verizon app and you'll see a screen promoting the offer. Follow the prompts to sign into your account, select the unlimited data plan that best suits you, then follow the steps to enroll in Disney+ once your new plan is official.
If you sign up as a new Fios or 5G home internet customer
To get in on the deal for free Disney+ as a new Fios or 5G home internet customer, you'll need to sign up for a qualifying bundle (as long as it's available in your area): the 2-year term Triple Play, 2-year term data and TV Double Play, or standalone internet data. Once your installation is complete, you'll receive an email with an access link to sign up for Disney+ and redeem the offer via the My Verizon or My Fios app.
It's worth noting that this 12 months of free Disney+ does not include the Hulu/ESPN+ bundle (which runs $13 a month). Still, though, it's a pretty standout deal when you consider it'll save you the $7 per month (or $70 per year) you would be paying to watch The Mandalorian, and oh so much more.
