    The transaction went well and the phone came quickly. Really neat condition, battery life feels short, with minimal use only lasts a good day. Fingerprint works fine for charging, but fails identification no matter how hard you try!

    Fast delivery with minimal packaging, which is great, and the phone is impeccable with no external defects. Fingerprint recognition not working. Screen capture not operational. Answering a call on the locked screen cuts off the call... Otherwise a pleasant, rather fluid device, I'm continuing my experiment.

    After 1 year of use the phone no longer works. The phone no longer charges and is beyond repair.

Refurbished OnePlus 6T devices

Where’s the best place to buy a cheap refurbished OnePlus 6T?

You’ll find the refurbished OnePlus 6T for up to 60% off the standard price at Back Market. If you’re on a tight budget but want to buy a high-performance smartphone at a low-price, shop with us.

You can´t go wrong with a refurbished OnePlus 6T

This high-end refurbished phone is checked before it’s put on sale to ensure it’s in perfect working order. Your refurbished OnePlus 6T is second-hand but will hardly show any signs of being pre-owned. You can choose a device with a few scratches or marks that will be cheaper than a mint-condition model (which will still be cheap!). And it’ll be wiped clean so there’s no old data on it.

The latest generation refurbished OnePlus 6T comes with:

  • A fast and powerful Snapdragon processor
  • A 6.41-inch screen
  • 6GB of RAM and memory of 128GB or 256GB
  • A dual-lens rear camera and a 16 MP front camera

Great quality, great prices on smartphones

When you buy a cheap, refurbished OnePlus 6T from Back Market it’ll come with certification and a one-year guarantee. We put all the devices we sell through a rigorous testing procedure and only use genuine branded parts if any need replacing. Your pre-owned phone will work just like a new one, but you’ll pay much less than if you bought a brand-new device.

Now you can own a state-of-the-art smartphone without paying full price. Buying with Back Market is easy. Just browse, select and click.
