    Okay, so. . . customer service acted professional in most cases except one, they had great communication, they were prompt in replies and were courteous but i'll get to the negative issue at the end, The phone iteself came very quickly in the post, great job there, and it was well packaged, The quality of the phone state, when I looked at the screen, it was very impressive for a second-hand phone, it looked brand new, no scratches, and when I turned on the phone, it looked even better, Now the negative customer service issue, Before buying the smartphone I asked the customer service agent for the exact android version of the phone, they replied that it would be either android 9 or 10, I said can you double check it yourself or with the seller? They said no we can't, I said if it's android 9 or 10 that's fine but I don't want it to be android 11, they said it would be 9 or 10, And when I checked the version after turning on the phone, it was 11, Now, because i'm tech savvy, I was able to modify the phone and install android 10, but here's the thing, most people would be pissed if they asked to have a specific version and not to have another version, only to find out that they ...

    So far so good, I hope it continues! The delivery time was respected. The smartphone is working properly, as long as it lasts. I had a very recent and very negative experience with another platform and the dispute has not yet been resolved... so I hope I won't have any problems with my purchase.

    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!

    Delivers what it promises. Minor damage to the casing (scratches and bumps). But working properly.

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.
