I have bought refurbished phones for at least 12 or so years. I wanted a s20 ultra to replace my s9+. I had bought 2 other s20 ultras fro different places but they did not work out. This phone is a keeper and I will have it for 2 to 3 years. Great phone!!

This is the second time that I have ordered from BackMarket and I have been very happy each time. The phone arrived in 3 days time with no issues. I would recommend anyone looking to buy a refurbished phone to buy from BackMarket.

Excellent delivery on time , great product, exactly what i ordered ,however (and this may be because this was my first time buying a refurbished device) but i had to unlock it myself due to it still being locked to att this may be something i as the customer should have researched beforehand but im not too swayed by that since the process of unlocking a device from att is actually quite simple easy and free courtesy of ATTs network unlocking request system but definitely something i didn't expect i had to do and luckily I didn't fall for the people charging for doing that. But otherwise the phone is excellent great condition works phenomenally battery life is practically speaking also phenomenal no shadows no on screen scratches or imperfections all around smooth and great purchase.

Ordered Galaxy S20 Ultra 5G - ordered the phone in excellent condition. And it is! Not a scratch or any sign of previous use observed. Also ordered fully unlocked and it was. Back Market staff were very good at keeping in touch and updated as to the status of my order. I highly recommend this company, the staff, their commitment to reducing E waste in the world and the products they provide.

Excellent. I first purchased on Amazon refurbished and received a poorly functioning locked phone from them. I then purchased from Backmarket and received an excellent phone quickly.

The S20 Ultra is perfect and no one would know it had been refurbished, it's a great model: light and with lots of features. I am very pleased with my purchase from Back Market! Thx!

This is my 3rd purchase from Back Market. Every phone has been exactly as described. This S20 Ultra is like new. The screen is immaculate and the body shows no scratches or wear either. The battery life is impressive. I like that it is backed by a 12 month warranty. I had no trouble transferring my data from my old phone with Samsung Switch. So far so good! I'll be looking to upgrade my daughter's phone soon, and will be coming back to Back Market to do so.

Renewed vs. brand new

Here’s what you help prevent, on average, by choosing a renewed smartphone over a brand new one.

171.1 lbs of CO2e

That's like driving an SUV from NYC to Chicago.

6.3 oz of e-waste

That’s around the weight of a baseball.

537.1 lbs of raw materials

That's like 20 dogs digging in your yard for a week.

20,341.2 gallons of water

That's like running a faucet for 3 days

Everything you ever wanted to know about the Galaxy S20 Ultra 5G

5G network speeds and 8K videos only scratch the surface of what the Galaxy S20 Ultra 5GSM-G988U 512GB Smartphone from Samsung has to offer. The quad-camera system features a 12MP ultra-wide, 48MP telephoto, DepthVision, and mammoth 108MP wide camera - plus a 40MP selfie cam. 108MP is so detailed that you can crop and print multiple images out of it without losing detail. The S20 Ultra can also get close - really close - thanks to a 100x Space Zoom that can pull out subjects you didn't even know were there. You can even snatch hi-res 33MP images from still frames within your 8K videos. A gigantic 6.9", HDR10+ certified, AMOLED 2X display is not just your viewfinder for saving memories, but it's also your portal for experiencing new moments with the latest in mobile entertainment. The nearly bezel-less Infinity-O display has no notch, just a small cutout for the selfie camera, helping to immerse you in your games and streaming video. Content that will look brilliant at 3200 x 1400 resolution, and run smooth with support for a 120 Hz refresh rate (up to 1080p). Powering everything is a large 5000mAh battery for all-day power. Under the hood, the Galaxy S20 Ultra runs the Android 10 operating system and sports a 7nm 64-bit 2.8 GHz processor, Snapdragon 865 chipset, and 16GB of RAM. Your 8K videos, 108MP shots, 100x zoomed photos, and more can be saved on the Galaxy S20 Ultra's 512GB of internal storage, which can be upgraded with an (optional) microSD card up to 1TB in size.
