Unlocking your Samsung device from a carrier can be hard, but not impossible! In this article, we’ll show you how to unlock Samsung Galaxy A03 for FREE no matter which carrier has locked your device, and get your Samsung unlocked easily.
To make the unlocking process possible we have created the Samsung Unlock Code Generator, an online tool that helps you unlocking your Samsung device by generating a unique NCK unlock code based on the device’s IMEI. Everything works online so there’s nothing to be downloaded or installed on your phone.
We do that by whitelisting your IMEI number in the Samsung’s database so your phone will be seen as official unlocked and will not be necessary to unlock it again even after factory reset is done. That’s exactly the same method network carriers use to unlock their devices to keep their customers as long as they can.
This can be done even you forgot your passcode, as long as the unlock code can be entered on screen-locked phones.

Carriers don’t like when you get your Samsung Galaxy A03 unlocked before your contract ends, so even if you’re paying them in advance there might be some other requirements such having a device that is reported as lost or stolen. So make sure to read and understand carrier’s unlock policy before asking for the Samsung A03 unlock code.
