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.
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.
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.
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.
If you already have an iPhone that you're looking to replace, consider trading it into Back Market to give you a little extra budget for your next smartphone upgrade. We make the process simple for you and we'll give you a free online quote when you answer a few easy questions about your current iPhone.
