Tech can get expensive, but luckily there are easy financing options! Use O2 financing for affordable payments that won't break the bank when you shop online. Pay a small portion up front, and spread the cost over 12, 24, and 36-month terms with 0% APR.

O2 financing is offered on a variety of products, including Apple AirPods, smartwatches, or even an Xbox or Nintendo Switch gaming console. To finance a new phone or tablet, you can spread the cost on a Pay Monthly contract with an airtime plan.
