I hae not figure the incoming call and call waiting yet but I am sure it will be not problem. Excellent phone even though it is refurbished. I will buy other things fro Back Market.

    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.

    Great purchase on my end, I was still using the S9 before this so it was due for retirement unfortunately, still love my S9 though. This S21 is better in several ways. even being refurbished. it charges in a bit over an hour, the back is plastic so you don't need to worry about the phone flexing in your pocket and cracking, an issue I ran into with my old S9 partly because I procrastinated getting a case. The cameras on this are great, the quality is nice, and I'm not sure which processor it uses but it runs really smooth. It's got the average 60 hertz display and the fast and snappy 120 hertz display that you can cycle through, 9/10 phone imo

    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.

    Arrived on time. Listed as "Fair Condition". When I opened the well packed box, my phone visually looked Brand New. No scratches no nothing. When I took my phone(Galaxy S21 5g 128) to my Service Provider there was NO PROBLEMS or ISSUES. I GOT MORE THAN I PAID FOR!

Reborn vs. brand new

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

That’s around the weight of a baseball.
