What does unlocked iPhone mean

An unlocked iPhone means that the device does not bind to a specific carrier and can be used with any mobile network provider that supports its hardware. This is especially useful when changing carriers, traveling internationally, or reselling your phone. There are four common ways to get unlocked iPhones: purchase directly from Apple, apply for unlocking from the carrier, purchase a third-party unlocking model, or use a SIM card to unlock services (but be cautious about the latter two). Unlocked iPhones still need to support the target carrier's frequency bands, and unlocking will not affect warranty or software updates. Having an unlocked iPhone brings greater flexibility and control, such as changing carriers at any time, finding more affordable packages, avoiding roaming fees, and increasing second-hand value.
