    The phone was packaged very well and is in perfect condition! If I didn't know it was a used/refurbished one, I would have thought it was brand new! Thanks for your great service.

    New phone works great, it was definitely worth the money. Only issue was the battery was trash. Thing kept turning off at 50% and depleting super fast. Spent 60 bucks on a new battery at a local shop instead of sending to the seller and waiting 2 weeks. Still cost less than the cheapest new iPhone

    Was so surprised to receive a basically brand phone . The only flaw is a tiny mark on the top of the phone but other than that I’m really satisfied :3 was my first time ordering from here and I’m very happy

    I am absolutely thrilled with my new iPhone! The sleek design, crystal clear display, and lightning fast performance have exceeded all of my expectations. The camera takes stunning photos and videos, and the battery life lasts all day long. The Back market App Store has endless options for customization and entertainment. I couldn't be happier with my purchase and would highly recommend the iPhone to anyone in the market for a new smartphone. It truly is a game changer!

    Although this iPhone had an issue that prevented me from keeping it (& which really caused me some stress, since it wouldn't stay on long enough for me to wipe my info) the return process was quick and relatively painless, & I got my refund. I don't blame the seller for a defective product, ofc; even factory-new phones sometimes have major glitches. I would (& have) used BackMarket again. If this seller has another item I wanted, I wouldn't hesitate to order it. 4.5/5

    Phone came in. Hardware wise, it's decent. No cracked or scratched screen. Some minor scratches on the back of the metal back, only noticeable if you look within 6 inches. However, I chose "Excellent Condition" and it says that the Battery should be over 85% guaranteed with that choice of purchase option. Yet the Battery was 79%. So that sucks. As I'm typing this review on the Back Market app, I scroll up on the review section and apparently, it says the condition is "Very Good". Which is not what I chose. Whatever. For a phone that's this old (and close to being no longer supported on cellular service), with the "higher end" color option, with a price of $95 before tax, it's alright. Delivery was fantastic though. Came in 4 days before the expected delivery date. Great experience for me, not guaranteed for anyone else though.

    I bought this as a gift for a family member in Columbia… The phone works perfectly but the battery that came with the phone must have been old or damage because the phone only stays charged for about 2 hours. The phone is in Columbia and there is no way for me to get the battery back to exchange it, which sucks. If you order a phone as a gift, I would suggest testing it out before you gave it away as a gift.

    I am very happy with the purchase. I bought it for my mom because she. She needed an a new phone and she didn’t want anything fancy. It is working very well, the camera quality is very nice and the speed of the phone is good as well. It’s a great phone for a low price especially if your on a budget

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 (:
