FAQs about Pv distributionized mobile installment payment

What is a Verizon device payment plan?

With the Verizon Device Payment plan, customers have the freedom to upgrade their device early and pay for their device in monthly installments over 24 months instead of paying the retail price all at once. While many other carriers offer a similar installment plan to comfortably pay for a new phone, Verizon's plan is unique in several ways.

Do I need a device payment Installment Agreement?

Customers should be aware that an installment agreement is required to purchase a device under the device payment Program. Device payment customers must also agree to the Verizon Wireless Customer Agreement, their calling plan, and other important terms.
