Part 1. Samsung Unlock Codes List for Free (For Models Pre-2015)
A Samsung unlock code is a numeric code used to remove a carrier's network restriction on your device. After entering the correct code, your phone becomes SIM-free and compatible with any supported network worldwide. Overall, there are three types of Samsung unlock codes.
NCK (Network Control Key)
The NCK is the primary Samsung network unlock code. It is a unique 8-digit or 16-digit number tied to your phone's IMEI. Its sole purpose is to remove the software restriction that ties your device to a specific carrier like AT&T or T-Mobile.
MCK (Master Control Key / Unfreeze Code)
If you or a previous owner entered an incorrect NCK too many times, the device will enter a "frozen" state to prevent brute-force attacks. In this scenario, the standard NCK won't work until you first enter the MCK to reset the attempt counter.
PGCK (Regional Keys)
Samsung often locks devices to specific geographic regions like the European Union or the Middle East. If you buy a phone in Germany and try to use it in the US immediately, you may require an RGCK to bypass the regional lock.
Understanding these code types helps you choose the correct solution and avoid unnecessary errors. Here is a Samsung unlock codes list, including 8-digit and 16-digit network unlock codes. But those Samsung unlock codes are only suitable for older Samsung models.

Part 5. FAQs about Samsung Unlock Code
Is it legal to unlock my Samsung phone with a code?
Yes, as long as the device is paid in full, carriers are legally required to assist with unlocking. But if your device doesn't meet the unlocking requirements, you cannot unlock a Samsung phone.
Will an unlock code wipe my data?
A network or SIM unlock will not affect your data unless you use some free Samsung unlock codes. However, most screen-unlocking methods, including factory resets or third-party software will erase device data unless a backup is available.
Can I unlock a phone that is still being financed?
Generally, no. As of the January 2026 policy updates, carriers like Verizon and AT&T strictly require the device balance to be $0 before they will authorize an unlock.
What if I bought my Samsung phone second-hand?
You will need to contact the original owner to have them request the unlock, or use a verified third-party service if the carrier refuses to help.

A Samsung unlock code provides a reliable and safe way to remove network restrictions and enjoy the freedom of using any carrier. Whether you get it from the original carrier or through some online free sources, following the proper steps above ensures a smooth and secure unlock experience.
