Phone is basically brand new. Which i did get in excellent condition and it shows it is. Doesn't even look like a refurbished phone. Connected to my service once we got it all figured out. Will definitely come back here for upgrades. 10/10.

Excellent phone. I purchased as condition 'good', and I would not expected more if I had selected 'excellent'. The only thing I think should have been done before shipping was 'factory reset'. There were some pieces of information that belonged to the refurbisher, and should have been wiped for the best startup experience. I did the factory reset, and phone behaved exactly as new out of the box.

I was skeptical about purchasing a refurbished phone. But I was glad I did purchase from Back Market. The transaction went soooo smooth from the purchase to getting it hooked up to T-Mobil. Best of all the price was right! Thank you so much...I would recom mend u guy's to friends that are looking for a new used phone. Ronald Hom

The phone functioned with the exception that it would not recognize the SIM. It was like new cosmetically. This is the 2nd phone that did not work with ATT. Nobody was able to help to make either of them work. The refund was timely both times. I have given up on refurbished phones though. I bought a new one instead from ATT that worked out of the box and with a trade in I spent 1/3 as much for a newer phone.

The Condition i pick was good and the phone came in like Brand new and it charged up with no problem so my first time on this website buying was great and i will keep buying more product from Back Market. 1 thing i do know is the reviews are very important when buying any item from here so for those who are afraid to buy from here its a safe site to buy from and the 1yr warranty is a plus so you don't feel like you got screwed, the seller i bought from had great reviews so i decided to give it a try. Galaxy S21 Ultra 5G 256GB - Black - Fully unlocked (GSM & CDMA MINT Condition when i got it. Deal with them People.

I'm actually extremely happy with my order! It was basically still in brand new condition! It looked as though it had never even been touched....the ONLY down side to that was the battery was completely dead on arrival so it took a bit to charge before I could even turn it on, but that was only a minor inconvenience. But the vendor made up for it as they seemingly gave me the highest end model of Galaxy S21 Ultra 5G on the market in the 512GB (I had order the 256GB). So yes 100% completely above and beyond satisfied perfect 5 stars, would give 6 stars or whatever comes next beyond awesome if I could!

The Galaxy S21 Ultra 5G 512BG arrived is just a bubble wrap sleeve wrapped in quite a bit more bubble wrap but it arrived in perfect condition. The Good rating was conservative. It took some effort to find a couple of case scratches. It could easily have been rated Excellent. The phone works perfectly with no dead pixels or camera issues. I prefer to buy unlocked phones rather than unlocked carrier phones to get update directly from the manufacturer. If I had to list a quibble it would be that this unit was actually an unlocked AT&T phone. It was a special that was not marked in the description, but for the price/condition offered, it was worth overlooking my personal preference. This is second Back Market purchase and second time with excellent results. I couldn't be more satisfied.
