I Was Very skeptical about ordering refurbished devices but my son ordered me an iPad from back Market last year and I love it it works perfect no problems so I decided to order the Samsung Galaxy S21 Plus so I would see how well it works and give you a review later just received it today November 9th 2023 very fast order because I ordered it on November 6th and 2023 and it said it will be here on the 13th and I got notifications that it was going to be here on the 10th and then another notification that he was delivered at my house on today which is the 9th so I appreciate I really like the service I recommend it to everyone and thank you very good I would recommend you

After having a phone for a year and a half the mother board went out. I was not going to pay that price again just to have it go out again. I was recommended to try back market refurbished. I bought a Galaxy S-21 Plus. It arrived in just a few days. Looked and operates like a new phone. I've had the phone for a little over 3 weeks now and the only problem I've run into is getting the right case for it. I keep ordering the wrong size. Right case is on the way. Should be here tomorrow. I'm so exited. Cross my fingers it's the right one this time.

Awesome phone at a competitive price. The S21+ I bought is in basically flawless condition and everything appears to be in full working order. I would absolutely make this purchase again a second time, and have no regrets. 10/10. Backmarket rocks and buying refurbished is the way to go.

I used to get refurbished through eBay. Then this time it was a two-time nightmare. I read a review for Back Market and I'm glad I did. The phone arrived quickly and has worked flawlessly. I will definitely use Back Market when it is time to upgrade again!

This phone is my 4th purchase from Back market and once again they over deliver. Phone works perfectly and dosent even look like a used or refurbished product. Even arrived sooner than the expected delivery date. I've never had a single issue with this company and I don't think I ever will.

Benefits of buying a refurbished Samsung Galaxy S21 Plus


At Back Market, customers save big compared to the price of new on certified refurbished Samsung Galaxy S21 Plus 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 Plus compared to a refurbished one.

Buying a renewed Samsung Galaxy S21 Plus is also a much better option for the environment. A refurbished Samsung Galaxy S21 Plus  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 Plus


You'll find the biggest selection, highest product quality and lowest prices on restored Samsung Galaxy S21 Plus 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 Plus 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 Plus deals on our platform. 

 

Samsung Galaxy S21 Plus warranty and return policy


All Samsung Galaxy S21 Plus 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 Plus


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 Plus 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 Plus 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.
