What's a Device Unlock
- Device Unlock lets you use your device with another carrier, for things like international travel or selling your device.
- Not all devices are compatible with every wireless provider; your device will need to support their network frequencies and technologies.
- This is different from Domestic or International roaming, where you use a T-Mobile SIM/eSIM to access a different wireless provider's network.
