The phone arrived in excellent condition, better than I expected for a refurbished device at this price point. It honestly looked new. Fully functional. Setup was simple, and everything works as it should. Battery doesn't last as long as the original and it gets a little warm with use but for anyone looking for an affordable smartphone for basic everyday use, a backup phone, or a first phone for a child, this is excellent value. Back Market provided an accurate description, fast shipping, and a smooth buying experience.

The iPhone 6S I purchased arrived in great condition. This was purchased for use as a work phone, and it suits that purpose very well. The phone works as it should, and the quality is on par for the condition rating it was listed under. This is my 4th phone purchase from backmarket, and I haven't been disappointed yet in the service or quality of phone purchased.

This was an amazing item to buy I never would have a thought a iPhone 6s would come with 97% especially when it's refurbished and I honestly see no scratches on the phone although I didn't receivea charger hopefully I can get one sent out but at first I was skeptical about back market because I didn't know what to except but when it came in the mail I was super happy so I definitely recommend back market.

I ordered a iPhone 6s for my 5 year old grandson. It came quickly and on the promised date. The phone is in very good condition and works well for him. I loaded it with pre-school apps and no sim card. I'm very pleased with the purchase.

I bought this older model iPhone for one reason only--to connect by Bluetooth to our stereo system to play WQXR radio. It replaces an ancient iPhone 6, whose battery swelled (for a second time) to a truly grotesque degree, and was no longer safe. The "new" iPhone 6s's condition was supposed to be medium (or something). It looked absolutely new, at least in our case. It worked. It was cheaper than another solution. Service was great. Review is therefore "Awesome."

My device looks great, works great, and battery seems to be in good health. I am only using the music portion of this phone. I am not taking pictures, video or making calls. Not using anything at all except the music.

The phone I bought was a iPhone 6s 32 GB, Space Gray in excellent condition. It came within two days of purchasing it and is stunning with seemingly no flaws other than a slight dent on the apple logo and very few scratches. It also came with a screen protector already on it, which was a plus in my opinion.

Iphone was just as described. I have bought a few things from back market & it’s never been any problems. Warranty is great & if you need anything such as replacement chargers or anything they replace it immediately.

Looking for a GSM unlocked iPhone 6s?

If you want a GSM unlocked iPhone 6s, make sure it is able to work on both AT&T and T-Mobile networks. There should be a little infographic below each product that displays this information :D

Is it worth getting an iPhone 6s in 2021?

You're probably not sure if this phone is still good in 2021. Not to worry! We wrote this article to tell you what it will be like using the iPhone 6s in 2021 :)

Looking for an unlocked iPhone 6s for sale? Or a deal on an iPhone 6s?

We have some of the best iPhone 6S deals on the web. All of our products are certified refurbished and come with an awesome warranty and money-back guarantee.

Released in 2016, the iPhone 6s was the refinement of the revolution that was the iPhone 6. Apple reinforced the metal body in response to the “bendgate” controversy that engulfed the iPhone 6. Due to these changes, the phone became more sturdy, but still kept those iconic antenna lines and overall marvelous design. Call me nostalgic, but in my opinion, this is one of the best-looking phones Apple ever made. And if you’re reading this, my guess is that you probably agree (:

Is buying an unlocked iPhone 6s a good idea? Let’s think about it together!

I know what you’re thinking. It’s not the newest iPhone. Will it still serve my purpose? I think so. Unlike the iPhone 6 before it, the unlocked iPhone 6s is upgradeable to iOS 14. This means that it should still be buttery smooth and feel new, despite already being a few years old. The cameras on this phone aren’t as impressive as the multi-lens solutions featured on the newest high-end iPhones, but if you’re not a photography geek, I think this will be enough for you. And we all know how Apple overcharges for more storage on new iPhones. You may as well get a version with at least 64GB so that you don’t run out of space when installing apps or taking pictures/videos.

Why Should You Buy a Cheap iPhone 6s Unlocked from Back Market?

If you shop used or refurbished iPhones on Amazon, you honestly don’t know what the quality of your device is going to be until you get it. The word “refurbished” has no universal meaning. Amazon doesn’t enforce any rules or checks on refurbishers. Products are often sold with underlying problems without being properly checked at a factory. For this reason, many people struggle to trust refurbished products.

But Back Market’s mission is to be the first refurbished retailer you can trust. Unlike Amazon, we have quality controls and checks to ensure that products are properly inspected and fixed (if necessary) before being sold. We give 12-month warranties included with our products to help you trust us, and we take care of any problems you may have with your device inside that period. We also give a 30 day money-back guarantee that lets you return your device within a month if there’s anything you don’t like about it! We know that sometimes things look different in-person than on a website.

Consider this as an informal little invitation to join our Back Market family (:
