This phone was finally delivered in Kampala, Uganda in East Africa after many days of travel. The juiciest part is that the phones looks premium even when I ordered for a “good” condition, it’s just a good one. God bless.

Had an expert who is a friend thoroughly examine it and it is basically a new phone. All original parts with exception of the back cover to protect battery. He said it was the most gorgeous phone he has held and examined all 2024 probably. 10 gold stars out of 10.

I'm still setting my S21+ up/getting it set with my new network provider, but so far - SO GOOD! I love how the phone & new charging cable came safely wrapped for shipment! My entire experience in searching for, as well as purchasing, a new device with Back Market has been a positive one. I get a strong sense of professionalism from the website, the mobile app, those who refurbish & those who pack to ship. My new phone is even better than I thought it would be in appearance & I have been recommending Back Market to EVERYONE as I have been preparing to send the device I'm currently typing on, in for a trade-in reimbursement! THANK YOU TEAM!

The phone is working fine, just like new--and the Samsung S21 is a good phone. The next time, though, I think I might go with a Good-rated phone rather than Fair-rated, as in this case. The phone has some markings around the edges, but that is a cosmetic issue, and has not affected the phone's performance. I continue to believe that BackMarket is an excellent online store for refurbished phones.

I bought this phone for my father, and it works perfectly fine. It did have some imperfections even though I did order Premium; it is refurbished so you can’t expect perfection. Overall great purchase. I will definitely be buying from BackMarket again.

I've bought from Rebeelo a couple times and everytime I've gotten a refurbished phone, it always had something wrong with it. Thankfully, Black Market can follow through with their promises of a functional phone. I'd most likely buy from here again

Received the phone on time with great tracking. I've had the phone a little over two weeks now and I love the phone. Came perfect, minor flaw that you can not even see. The transfer was super easy and fast. Called my provider and was able to get my phone service on the new phone easily. I purchase a galaxy watch from here and was impressed I am super glad I purchased the phone now. Would definitely recommend this to anyone.
