This is the 2nd Samsung smartphone we bought from Back Market. This Samsung Galaxy S21 5g Unlocked 256gb was listed as Fair condition and besides the few scratches on the back of phone, you would have never known it was a refurbished phone.

I was in the market for a new phone and was very seriously considering taking out one of those "loans" from Smart Pay so I could purchase a decent phone. That was until my coworker told me about Backmarket.com! I was very hesitant at first about ordering a refurbished phone but once I did some research, I decided to take a chance and I ordered the Samsung Galaxy S21 5G 128GB in Phantom Violet, "Good Condition". My new phone arrived this morning and OMG - I am absolutely BLOWN away!!! It looks fantastic! There are hardly ANY visible scratches except for one small one on the front (the back looks flawless), it was extremely easy to transfer over from my old phone, delivery was super quick, and I just simply cannot express how HAPPY I am with my purchase! I am beyond grateful to have found Backmarket.com! I will update/write another review in about 1-2 weeks once I have had a chance to REALLY see what this phone is all about. But like I said, at first glance, I AM ECSTATIC! Thank you, Backmarket!!!

The product was in perfect condition. So perfect that it was still locked to Verizon. I bought it as an unlocked phone, so I was surprised, and a little frustrated that I couldn't activate it because it wasn't compatible with my network or any of the other 5 networks that I tried. I finally discovered it would only work with Verizon. Verizon claims their phones are not locked, however, in an attempt to prevent theft, all of their products have to be used on a Verizon network for at least 6 weeks be for it's unlocked to any other network. I learned of this when I took the phone into Verizon to find out if it could be unlocked. I panicked because I feared they might think I had stolen it. Fortunately,Back Market provided easily accessed proof of purchase, and I was able to work with a multi-store manager when I went into my local Verizon store. After an hour of working on the issue I was having, he was able to trace the serial number and determined that this phone had most likely been returned due to a problem with the battery. It had then been legitimately sold to a person or company who refurbishes such products for resale. So I'm giving this experience 3 of 5 stars because ...

This phone is amazing. It was delivered within 4 days and it was handled with a lot of care! I wouldn't have even guessed that this was a refurbished phone, it seems like it's brand new! I highly recommend buying all of your tech from Backmarket, it's extremely reliable and I am definitely buying more from here in the future.

I always purchase refurbished tech and I'm always very pleased. This purchase has been another great but. The phone looks and works like a new phone at like 75% less than if buying new. Why wouldn't you go this route? It's so much better!

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.


Where to buy a refurbished Samsung Galaxy S21


You'll find the biggest selection, highest product quality and lowest prices on restored Samsung Galaxy S21 5G models at Back Market. That's because we specialize specifically in refurbished tech and take the time to carefully vet every seller on our marketplace to ensure customers are getting reliable devices that perform like-new. We have hundreds of refurbed Samsung Galaxy S21 5G phones in price ranges to fit almost anyone's smartphone budget.

Staying true to our brand, we're also a huge advocate for environmental change. In fact, at the beginning of 2023, we hit a milestone for preventing 1 million tons of carbon emission (CO2e) from entering the atmosphere. You can help contribute to a better circular economy when you shop Samsung Galaxy S21 deals on our platform. 

 

Samsung Galaxy S21 5G warranty and return policy


All Samsung Galaxy S21 5G purchases on Back Market come with free standard shipping, a 1-year warranty, and a 30-day money-back guarantee. We want to make sure you can shop with confidence and find the best Samsung Galaxy for your needs at lower prices.

 

What to expect when buying a refurbished Samsung Galaxy S21 5G


If you're a first time refurbished buyer, you might not be sure what to expect from your purchase. First, understand that your Samsung Galaxy S21 may have external cosmetic flaws depending on the condition you choose (Back Market offers devices of Fair, Good and Excellent quality). However, whatever the condition, any external blemishes will not affect the performance of your Samsung Galaxy and you can expect your device to perform as if it were newly opened directly from the Samsung Store.

You should also be confident that your Samsung Galaxy S21 is backed by a 1-year warranty, meaning in the rare case that any defects arise (outside of accidental damage) within 12 months of your delivery date, then you're entitled to your choice of a repair, replacement or reimbursement. 


Smartphone Trade In


If you already have a smartphone that you're looking to replace, consider trading it into Back Market to give you a little extra budget for your next smartphone upgrade. We make the process simple for you and we'll give you a free online quote when you answer a few easy questions about your current smartphone.
