    I got this phone for my youngest daughter and as a test to see how ordering a refurbished phone would go...to my surprise this iPhone 8 really was in excellent condition. It looks brand new and The battery is lasting her all day too. The day I received this phone, I came back to order a different phone for myself, and it arrives today. I am very excited and I would absolutely recommend buying from back market, I plan to buy an iPad soon and will be shopping from here when I do. I love the fast shipping too.

    I'm loving this vintage iPhone 8... so thin, lightweight, and with the original design language that everyone loved; the home button, swipe to turn off, the silent mode switch, etc. This phone came as described virtually as it came brand new, no scuffs, blemishes or scratches. I'll certainly be using Back Market for future tech goodies!

    There’s no other company in the world that i trust more than backmarket to get me a decent apple product at a decent price. I never use to shop refurbished but this site is top tier. Everytime I order my product is always in perfect condition no matter if I order excellent or good. I will forever be a customer.

    I love love LOVE being able to purchase these refurbished items. I use this for all of my phones and tech and I haven't been let down yet. I bought a brand new laptop for $1200 from a manufacturer and it lasted less than a year, but everything that I bought from here has worked so well for the past 5-ish years! I work in IT so I started buying here figuring that I could just fix this cheap stuff as it breaks but (knock on wood) everything has been working great! The only issue I have ever have has been Apple killing the battery of old phones with updates, but they do that even with non-refurbished stuff. I feel a lot better spending $200-$400 every 3 years for a new-to-me phone instead of $800-$1500. My whole family uses it now too because saving money and preventing electronic waste is awesome since being green usually costs more instead of less. What a great deal!

    I opted for the Premium tier for the longest battery life and it's not quite what I had hoped for. Pretty good. Good price. Happy to use a refurbished phone.

    The phone has a few quirks. It has a jumpy screen when I try to enlarge. Suddenly goes dark from time to time. Does not show missed calls. Shows the red dot, but doesn’t list them. If I turn my phone off, then back on then I can see them. I still stand up for refurbishing a phone instead of staying in debt to have a new one. Makes no sense to me.

    Shipping and packing were excellent. Phone arrived in great shape/looking new. Appears to even have the protect screen already present. Battery charged to 93% and that is stellar for a rebuild. Would buy again, for sure. Super nice deal on the iPhone

    I ordered an iPhone 8 listed as being in excellent condition, but what I received was far from it. The battery showed 88% capacity, yet the phone couldn’t hold a charge for more than an hour. It was basically unusable out of the box. I had to take it to an Apple Store and pay to have the battery replaced, which completely defeats the purpose of buying a refurbished phone. If the battery is that weak, it should be disclosed or replaced before selling. Not happy with this purchase.

Should I buy an unlocked iPhone 8?


When you buy an unlocked iPhone 8, 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 8 at a low price.

Locked vs Unlocked iPhone


Which networks can I use an unlocked iPhone 8?


Your unlocked iPhone 8 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 8 warranty and return policy


All locked or unlocked iPhone 8 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 8 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 8


When you buy an unlocked iPhone 8 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 8 might look slightly depending on the network, but you can learn more about the activation process on our help page.
