You can use the BOGO credit on any version of the iPhone 12.
Brad's Deals Editor Michael,
New customers who purchase an iPhone 12 and open a new line of service with an Above, Beyond, Do More, Play More, or Get More Unlimited plan at Verizon will receive an $800 credit that can be put towards a second iPhone 12. You can apply the credit to any iPhone 12 device, but only the standard iPhone 12 and the iPhone 12 Mini will have their full prices covered by the credit. This is the best deal we could find for anyone looking to purchase two new iPhones on Verizon. As a bonus, you can stack on Verizon's current trade-in offers on this deal and save up to an additional $550. Shipping is free. Sales tax is charged in most states.
