So far so good. The only thing that had me worried was when I turned on the phone it displayed xfinity. I was confused because I bought an unlocked phone but after some research I saw that unlocked phones can still have previous service providers installed on phones...or something of that nature. As long as it works...

Absolutely happy with my purchase. There was a delay in shipping, but Backmarket reached out and kept me informed all along the way. That is why I keep coming back after all these years! I highly recommend Backmarket to everyone who will listen!

Was worried I was gonna get what I paid for, because everywhere I went this phone was $500+ and to spend 1/4 of that and to have a awesome phone that has not disappointed me once . Very pleased would use BackMarket again if I need to do so.

I have used Back Market multiple times for different refurbished electronics & they have always done a great job! All our phones & laptops have been in great condition & the website is easy to navigate. I recently purchased a Samsung Galaxy S21 FE 5G 128GB & it is great & shipping was pretty quick.

I purchased a Samsung Galaxy S21 FE 5G in excellent condition. That's exactly what I received. The only complaints that I have is the small battery size and the fact that it's not ESIM compatible. However, the price was lower than you would find anywhere else. Thank you Back Market for your business!

Great phone, like new condition, updatable to One UI 7.0 and Android 15. Super fast shipping! Always get great gear from BackMarket (just wish I didn't break my phones so often that I'm such a good repeat customer for them!)

It's in really good condition, looks like it's brand new, and I can't believe how lucky I was to get it. And it comes unlocked just as described. What I would have liked is for them to have specified that when you turn it on, it displays the logo of the company that used the phone before it was unlocked. But the phone is 10/10, I plan to get more products from you and send them to my relatives in my home country.
