I took a chance on ordering a "fair" condition phone because my old Galaxy S8 was run over by a car and the screen was broken enough to make it unusable. But, I didn't have the money to spend much for a new phone. The condition of this phone is amazing for the price. There is one very small crack on the side of the phone that I barely even notice and the battery life is as good as my old one. I will definitely be back for my 3rd phone from BackMarket when the time comes! Thanks!

I was a little apprehensive about the nonspecific, generalizing about the classifications of the phones: ie. Fair, Good, Excellent. My particular phone did not have one in Excellent so opted for Good. I was pleasantly surprised. The phone was seemingly new!

Transaction, Service, and shipping Great. Unfortunately the seller did not mention the image burnt into most of the screen. I'll be back, and have already started promoting your website! Please keep an eye out for those shady refurbushers!

Product in excellent condition. Arrived quickly and price is right. My only issue - it is an unlocked phone but was originally a T-Mobile phone and the app for T Mobile cannot be removed so the phone starts up with the T-Mobile logo and sound - when I am using the phone on Verizon

Is the unlocked Samsung Galaxy S8 a good phone?

From my experience, every premium device sold by Samsung will give you quick performance and customization. Even though you won’t get the newest Android version on the unlocked Galaxy S8, you’ll still have a phone that feels modern and works great. Samsung is praised for their screens; they’re great for watching videos because of their amazing color contrast and OLED technology. Also, if you’re tech-savvy, these phones are great for “rooting” because of their impressive specs and developer support.

What if I don’t like my unlocked Samsung Galaxy S8 after buying it?

This is why we suggest buying all your devices from a dedicated refurbished retailer like us here at Back Market :) We offer a 1-year warranty on refurbished phones and a 30-day money back guarantee just in case you’re not 100% satisfied with your purchase. And since these models are unlocked, they’ll work for just about any carrier here in the US. Verizon, AT&T, T Mobile, we got you covered :)

What's the best place to get an unlocked Galaxy S8 for sale?

We believe we're the best place to get an unlocked Galaxy S8 for sale because our phones are much cheaper than new releases, while offering the same quality thanks to our certified refurbished program.
