Refurbished OnePlus phones, unlocked and tested

Our refurbished OnePlus collection gives you flagship-level speed for a fraction of the new price. Each used OnePlus unlocked device passes our TrueGrade 25-point inspection, which checks the screen, battery health, cameras, buttons, charging, and network hardware before it goes up for sale. If a phone does not meet the standard, it does not ship. That is how we keep quality steady across the OnePlus 8, 9, 10, 11, 12, and the budget-friendly Nord line. Whether you want a daily driver or a phone you can hold onto for years, buying refurbished OnePlus is one of the easiest ways to save real money.

Unlocked means you pick the carrier. Every OnePlus here works on AT&T, T-Mobile, and Verizon, plus prepaid and MVNO plans like Mint, Metro, and Cricket. Just move your SIM or activate an eSIM and you are set. There is no contract to sign and no carrier lock to work around. Prices run up to 70% cheaper than new, so a renewed OnePlus is one of the smarter ways to get fast charging and a clean OxygenOS experience without paying flagship money. If you have been eyeing a used OnePlus unlocked and holding off, this is where the value lives.

Which OnePlus model fits you

OnePlus has kept a fairly simple lineup over the years, which makes picking a used model easy. Here is how the main options break down.

  • OnePlus Nord: the value pick for everyday use, calls, streaming, and social apps without overspending.
  • OnePlus 8 and 9: strong all-rounders with fast charging and clean software, now at their best prices.
  • OnePlus 10 and 11: more camera and gaming headroom for heavier users who push their phone hard.
  • OnePlus 12: the newest flagship power for those who want to keep a phone for several years.

If you already know the model you want, filter the collection and check the grade on each listing. If you are open, the OnePlus 9 and 10 tend to hit the sweet spot of price and performance for most buyers.

How Device Giant grades every phone

Every phone gets a condition grade so you know exactly what you are paying for. Cosmetic wear does not affect how the phone works, since all functional testing is the same across grades.

GradeWhat to expect
ExcellentVery light or no visible wear, fully functional
GoodMinor cosmetic marks, screen and body sound

Frequently asked questions

Are these OnePlus phones unlocked for any carrier?
Yes. Every OnePlus we sell is unlocked and compatible with AT&T, T-Mobile, and Verizon, along with prepaid and MVNO plans. You can bring your own SIM or activate an eSIM. Always confirm your plan supports the bands you need before switching.
What does refurbished mean at Device Giant?
Refurbished means the phone has been inspected and tested through our TrueGrade 25-point process, then graded by condition. We check battery health, screen, cameras, charging, and network hardware. If a device does not pass, it does not go up for sale.
How much can I save on a used OnePlus?
Pricing on refurbished OnePlus phones runs up to 70% cheaper than buying new. The exact savings depend on the model and grade. Older models like the OnePlus 8 and 9 offer the deepest discounts, while the OnePlus 12 holds more of its value.
Can I return a OnePlus phone if I change my mind?
Yes. You have 90 days from delivery to return your phone. If it does not work out, contact our team and we will help you sort out the return. Keeping the box and accessories makes the process smoother.
Do refurbished OnePlus phones come with the original box?
Boxes and accessories vary by device since these are pre-owned phones. Listings will note what is included. Every phone ships with what it needs to power on and charge, tested and confirmed working before shipping.
How fast is shipping?
Shipping is free and tracked within the US, sent from our Coppell, Texas facility in the DFW metro. You will get a tracking number once your order is on the way so you can follow it to your door.
