The SIM card tray was cracked along the edge and it was tricky to reinstall without further damage. Luckily I had an old S8 and I swapped the trays. Other than that the phone functions as expected. 4th purchase on BM 1st issue.

Phone did not work. Spent hours on phone with my provider and at the end of the day nothing. Refund could take over a week and my other option is to buy another and get a refund after I send other back. Why would I want to spend more money buying from you guys when my first experience was so very bad.

I ordered a fair condition phone but felt almost new. It had just 2 micro dents on the frame which were hard to notice. Battery backup is good and easily lasts a whole day for medium use. A full charge gives a solid 3 hours screen on time or 2.5 days on standby

Phone looks great. Paid the extra money for 2 day delivery, but it ended up taking 3 days. I know that doesn't sound like a big deal, but when you're without a phone - it is. That being said - I am very happy with the phone.

Pretty good, I didn't expect interface/experience differences between T-Mobile and Unlocked versions of the S8 but I'll adjust. Only issue was a black spot of no screen in the bottom left of it's display, otherwise its perfectly fine and a great deal for the $67 I paid.

The customer service is great! Shipping was right on time, happy with that. Phone looks great, however; the volume is so low I have to put it on speaker to hear when on a phone call. My previous Galaxy S8 was fine, I had no problem hearing.

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 :)
