    I was looking for a convenient phone just to have because I recently broke mine and needed to have something on hand. I was a little nervous with using the Back Market app because I’ve never thought about buying refurbished electronics but so far the phone has given me no issues. I will continue to use backmarket whenever I need something quick and affordable.

    I've never used refurbished before but I must tell you the experience I've had has been great. Ordered an IPhone and it was delivered on time and in great condition. We did have an accident and had to return the phone. No problems with the warranty easy to follow and Back Market stayed to their word. I have reorder another phone. Great Job Back Market.

Work, life, and taking pictures is part of my job and this refurbished I phone X did the trick! Thank you Back Market !!! I am now purchasing another phone to further my work in life. I will keep using Back market over and over until I get my dream phone on my time. That' s the best thing my dream phone on my time. It works folks. And, Back Market buys your old phone for a few bucks back in your pocket!!!!

    My Iphone X is great. The battery lasts allot longer than my previous phone. I didn't want to spend money on a new battery for my previous phone (Iphone 8), I wanted an upgrade. You have been gaining recognition because of your great service and quality refurbished phones and other electronics; love your online ads. I feel that Back Market as a company will grow much larger. I've been recommending your website to others and even had my wife purchase a phone from there. She loves her phone. Thank you

    I purchased this phone for my 9 yr old. It looked new with little to no scuffs or scratches . It held battery as expected for an older gen iPhone. I was so happy with the purchase I came back to purchase a MacBook I've been wanting. If that works out they will definitely have a lifetime customer!

    When my phone arrived, I was very surprised. I had previously tried to buy from this site twice, but ultimately decided against it because I was wary of buying a phone here. But from now on, I will continue to buy here. The service was excellent. It arrived very quickly, the customer service was excellent, and above all, I loved the phone; it's like new! It also has 100% battery life. I 100% recommend buying here. I always take reviews into account before making a purchase. They've helped me. And I hope my honest opinion helps you make the decision to buy here! You won't regret it! Thank you!

    Great condition, cute packaging, easy to set up. incredible price! I don't understand why one would buy full price when they can get something just as good for a fraction of the price. I love my Back Market.

    It came fast and without any problems with it. I'd prefer something rather an a Apple product but my hearing aid manufacture only compatable with certain manufactures for the model of hearing aid that I have and it's alot cheaper to replace the phone than the hearing aids. Haven't ran into any problems with Back Market. Everything has been above par.

Should I buy an unlocked iPhone X?


When you buy an unlocked iPhone X, you'll have multiple options for choosing a carrier network. It is the safest option if you're not already locked into a long term contract with a network like Verizon, T-Mobile or AT&T. With an unlocked phone, you also have the option to easily switch between different network providers if you need to.

However, if you're happy with your current network provider and you don't plan on switching any time soon, you might save a little more money by shopping for an iPhone locked to a carrier. Locked phones tend to cost less than unlocked phones on average.

Whichever you option you pick, Back Market has plenty of options to help you find an iPhone X at a low price.

Locked vs Unlocked iPhone


Which networks can I use an unlocked iPhone X?


Your unlocked iPhone X from Back Market will work with all 3 major carriers in the US: AT&T, Verizon and T-Mobile. Since it is compatible with all 3 networks, you can also activate it under each of their Mobile Virtual Network Operators (MVNOs) including Mint, Straight Talk, US Mobile, Cricket, Boost Mobile, Google Fi, Metro and others. 

 

Unlocked iPhone X warranty and return policy


All locked or unlocked iPhone X purchases on Back Market come with free standard shipping, a 1-year warranty, and a 30-day money-back guarantee. We want to make sure you can shop with confidence and find the best iPhone X for your needs at the lowest price. In the rare case that any defects arise (outside of accidental damage) within 12 months of your delivery date, then you're entitled to your choice of a repair, replacement or reimbursement. 

 

What to expect when buying a refurbished unlocked iPhone X


When you buy an unlocked iPhone X from Back Market, you'll be receiving a phone that has not been activated with any network yet. It's still a fully functional device, but you will not be able to make any calls, text or access the internet without Wi-Fi until it has been properly activated with a carrier of your choice.

Activating your iPhone X might look slightly depending on the network, but you can learn more about the activation process on our help page.
