    I recently purchased a refurbished Samsung Galaxy S21 from BackMarket, and I couldn't be happier with my experience. Here's a breakdown of my thoughts The phone arrived in excellent condition, just as described on the website. I opted for the "Excellent" grade, and true to its word, the device looked almost brand-new. There were no noticeable scratches or signs of wear, and the performance has been flawless so far. Pricing The pricing was very competitive compared to buying new or from other retailers. I saved a significant amount without sacrificing quality, which made it feel like a great deal. Shipping and Packaging The shipping was fast and efficient. The phone was securely packaged, ensuring it arrived in perfect condition. I appreciated the eco-friendly packaging, which aligns with BackMarket's commitment to sustainability. Performance The Samsung S21 is a fantastic phone with a vibrant display, excellent camera quality, and speedy performance.

    The phone was in excellent condition. I had no issues swapping phones and have run across no glitches. I am very pleased. As someone who doesn't need the newest item, just a good functioning one, I am pleased to find a place I can find refurbished items without worry.

    Got the Galaxy S21 5G 128GB unlocked (ordered the "excellent condition") and have used it with my Straight talk service for a few weeks now.. So far perfect! This is the second time I have ordered a phone from this website and have been happy both times!

    Only a single small scratch along the top. Otherwise flawless, even without a case the scratch is barely visible, I was so afraid of buying anything here but I definitely will be looking for other products now, when I hear refurbished I usually see badly finished products. When back market refurbishes something it is flawless

    I was skeptical About buying a refurbished model but everything turned out great.The phone is an awesome condition.And it came with a screensaver already on the phone. There was no problems in updating the phone or getting it programmed correctly.

    So I tell you what I bought this phone of a back market for about $250 tops for shipping and everything anyway I'm pretty satisfied but I understand if this is a used phone and there are some trade offs anyway phone wasn't perfect condition not a scratch not a blemish nothing perfect physical condition the only thing I could complain about with this phone because I feel like you can see the screen was replaced and when it's completely black you notice a little smudge underneath the glass which is understandable because it is refurbished phone which means screen could have been broken before but you only noticed this when it's fully black when you have a full black screen also I don't know what charger is I'm using exactly but I noticed that it fast charges at first and then goes to Regular chart realistically fast charge only saves you 20 minutes from regular charge other than that software has been spectacular exactly what you would expect from a Flagship Galaxy device your phone is great it is meant to do what it does and does it well also I noticed a little nitpickio though is that when you use Snapchat and you zoom in for the first time and you zoom out there's a slight lag so ...

    Delivery was on time. The phone itself came with a screen protector already on. (that was so nice) It has one or two little scratches on it but that is to be expected because its refurbished. Honestly once you put a phone case on you cant see it anymore. All in all I would recommend backmarket to friends and family. I'm so happy I got my Andrew (android) back lol!

    I have purchased from BackMarket before (back in 2021) and loved my S9+! I recently decided to upgrade to the S21 and, of course, knew that BackMarket would be my best option! This time around I decided to go with the, "Good" condition option (went with "Excellent" for my S9+) and I'm honestly very, very pleased. There are a few scuff marks on the back of the phone, and there's a slight scratch on the screen, though neither are very noticeable! All in all, I would (and do!) - highly- recommend buying refurbished, and buying refurbished from BackMarket at that!

Benefits of buying a refurbished Samsung Galaxy S21


At Back Market, customers save big compared to the price of new on certified refurbished Samsung Galaxy S21 5G models. The best part is, you don't have to sacrifice performance quality in order to save money; all refurbished devices on our marketplace have been fully reconditioned, cleaned, inspected and tested to the same standards as a new one. This is the biggest difference between buying a used or pre-owned Samsung Galaxy S21 compared to a refurbished one.

Buying a renewed Samsung Galaxy S21 is also a much better option for the environment. A refurbished Samsung Galaxy S21 5G is often a second-hand device that has been restored and updated to meet the Samsung's manufacturer standards, which means you'll be helping to keep old Samsung Galaxy's out of our landfills, reduce electronic waste, and minimize your carbon footprint.
