An unlocked iPhone is an Apple phone that is not tied to a specific carrier or network. This means that it can be used with any compatible carrier that supports the iPhone, as opposed to a locked iPhone, which can only be activated on a specific network like Verizon, AT&T or T-Mobile.
Opting for a fully unlocked iPhone gives you more flexibility to choose any phone service that gives you the best coverage or saves you the most money. Having the freedom of an unlocked phone is also particularly advantageous if you travel abroad often and would like to use local SIM cards to avoid expensive roaming charges.
At Back Market, the unlocked iPhones on our marketplace typically save our customers 30-70% on average compared to the price of paying for a new one. We take the time to make sure that the sellers on our site have properly refurbished these phones to a like-new condition. They've been repaired, cleaned, inspected and thoroughly tested to make sure you're saving money on a quality device that you can use with any compatible carrier.
All multi-carrier iPhones on Back Market come with free standard shipping, a 1-year warranty and 30 days to change your mind. We're also here to help you through the process of activating any unlocked smartphones that you've purchased, which we know can be intimidating, but is actually a very simple process. If you want to do it yourself, make sure to check out this article on activating your unlocked phone.
