Unlocked devices can generally be used on any compatible cellular network, rather than being restricted to one specific cellular provider.

A phone can be factory unlocked, meaning it’s originally sold as unlocked. Or a phone can be carrier unlocked, meaning it’s originally just for one carrier, but is then unlocked by that carrier for broader use on other carriers (such as an MVNO).

On Swappa, our unlocked device categories are for factory unlocked devices that are not and were not previously restricted to a single carrier.
