More About O2

Redeem an O2 Promotional Code

Use a promotion code at checkout if you're about to purchase a new Apple Watch, AirPods, or another device and phone accessories. You can shave the costs of your next purchase and get the discount you deserve.

O2 Financing 

O2 understands how pricey tech can get, so it worked to propose a financing option without draining your bank balance. When you buy a device with O2, you can now spread its cost into affordable monthly payments. Plus, with 0% APR, the price you are seeing is the price you'll be paying. 

You can start with a small payment upfront and spread the rest over a period of 12, 24 or 36 months– ultimately depending on the device you choose to purchase. For more information on how the O2 financing works, click here, or to read through the FAQs, click here
