Unlocked phones are designed to work with any network, allowing you the flexibility to switch SIM cards between different carriers without affecting the unlock status of the phone. This makes them ideal for those who travel frequently or prefer to switch carriers to take advantage of different plans or coverage. However, always ensure your device supports the network bands of the new carrier for optimal performance.
