Seller is SimplifiedDeals and they have been excellent to work with. Received Galaxy S8 in unlocked and excellent condition as requested. Bought a second phone from them and the return process was smooth. Will purchase other phones from this particular seller on Backmarket.

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 ...

The phone arrived quickly and better than just "fair." I cannot believe how great the device is for a refurbished.

It was bought in good condition and it was in exceptional condition when I received. The shipping was fast as well and the phone works like new. I recommended it to some friends and they are about to make their first purchase.

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?
