    Love BackMarket! Lol love the new commercial/ad too! I’ve purchased quite a few devices over the last couple of years. From iPhones, galaxy phones, iPads and more im not thinking about I’m sure. They make great gifts… what’s even better they are refurbished and not some trash floating in our oceans and in our landfills. Every single device I’ve purchased is still being used and in perfect working order. Will never buy brand new again. I’m not one who likes the price tag of brand new items these days. So thank you backmarket team! Keep up the awesome work. Maybe throw some coupons to the repeat customers once and a while lol.. (worth a shot, lol) I’m a bargain hunter 😉

    Ordered black galaxy s9 excellent condition to use for trade in, received a blue s9 slightly below excellent condition. Trade in was still accepted, but quality control could be better. Also would’ve messaged customer service but the system routes and directs in a way that makes that difficult.

    When I bought a Galaxy S9, I was assured that "most" service providers would accept it. I went to Spectrum where the agent helped to cancel my Gov't phone service and set up the S9, BUT then he said oh sorry Spectrum doesn't provide for that model. Things got confusing, since I knew I'd put the S9 on my credit and would need to return it. HOWEVER, the agent told me that if I traded it in, I would be elegible for a promotional that ends up with a new phone, the Motorola RAZR for free (!) I have confirmed that there was no misunderstanding. So I will pay for rather than return the S9. I appreciate being able to cancel the extra warrantee. Thank you.

    I would give this transaction 6 stars if I could. This phone literally looks factory new. Original Samsung packaging and documentation included. It even had the OEM looking screen protector on it. On time shipping and great price as well. Job well done BackMarket.

    The phone was packed securely to prevent damage in transit and arrived in great condition. The phone looked practically brand new. It had almost zero scratches. The phone had been factory reset and all evidence from any previous owner had been completely wiped from all system data folders. I would definitely buy from this vendor again!

    Came in factory packaging, but had a bit of some kind of powder it seemed around the crack in the edge of the phone and something in the speaker causing it to sound a bit tinny but it ended up resolving itself. Couple days after buying I try the selfie camera and it's as if there's a cataract over the screen. Hopefully I can get a repair.

    Been using backmarket for years now. As always, my order was perfect. Typically I'll just buy older phones for use with trade in at T-Mobile. I can always count on the quality being perfect for getting a trade promo!

    It came looking brand new. However: 1) The battery drains extremely quickly so I have to keep it plugged in from about 1 pm. 2) The camera is not as sharp as it should be. I bought it to replace the same phone I had before, and the pictures from this one are lighter. I checked if there's a plastic I haven't removed but there isn't, so I guess that's how the camera on this one works. I'm not returning it because I dropped it and it got a crack so I certainly don't expect them to replace it. For the price I paid (around $130) I would probably do it again, but this time I'm aware that buying a refurbished phone is not exactly like buying a new .

    Phone was in excellent shape. Also, It arrived 3 days early. First purchase through Black Market, and expect to use them again in the future.

Is the unlocked Samsung Galaxy S9 a good phone?

Yes, it is. Unlocked Galaxy S9 phones are known for their amazing screens and smooth interfaces. Fun fact: Samsung screens are so good that even Apple buys Samsung displays for their new top-of-the-line iPhones. Impressive, huh? I’d say so. Also, Samsung is known for having some of the smoothest versions of Android. It’s really hard to find a bad Samsung device. And since these phones are unlocked, they’ll work on just about any carrier. Verizon, Sprint, AT&T, T Mobile—we got you covered. Don’t worry, we don’t have favorites, we want to help you no matter what carrier you use!

What’s the best place to find an unlocked Samsung Galaxy S9 for sale?

Amazon doesn’t check their refurbished retailers for quality. Or give extended warranties. That’s bad news. But I have good news for you too… Back Market provides all of these, free of charge :) We’re so nice, right?

What if I want a GSM unlocked Galaxy S9?

When you're buying a GSM unlocked Galaxy S9, you're getting a phone that can work on any GSM carrier such as T-Mobile, AT&T, Cricket, Metro, and probably most European and international service carriers.

Looking for a cheap unlocked Galaxy S9 for sale?

Back Market is the best place to get your next unlocked Galaxy S9 for sale. Why? Because our phones have a similar price to equivalent used Galaxy S9 phones, while coming at a quality equivalent to new models. Pretty cool, huh?
