Samsung Galaxy Z Fold 6 / Z Flip 6 Network Unlock Code NCK Instructions. How to Get Your NCK Unlock Code & Remove Carrier Restrictions.

Writer's picture: The Lock ShopThe Lock Shop

Samsung Worldwide Factory Network Unlock Code (Network NCK + Defreeze MCK)


The following set of instructions will remove the carrier network lock on your device - EVEN IF THE DEVICE IS STILL CURRENTLY FINANCED & ON A PAYMENT PLAN.


This will unlock the SIM & eSIM of the device.


*If you want to unlock your own device, please see list of unlocking servers at the following link: HERE


UNLOCK PROCESS - For Network (NCK) Unlock Code

*This process will get you the NCK (Network Unlock Code) & the MCK code, or Master Control Key The MCK code is a special unlock code that is used when the standard network unlock code doesn't work, usually due to multiple incorrect attempts.

*This is only for carriers  like AT&T or Verizon that require an unlock code. Carriers such as T-Mobile use the T-Mobile device Unlock App meaning no unlock code can unlock Tmobile devices. See our "Device Unlock App Service" for explanation.


STEPS


1. Either you or your customer place another sim card in the device (not the original carrier sim card) and see if the device requests a network unlock code to continue. If the device asks for an unlock code this will work. If your device does not ask for a network unlock code this will not work. If T-Mobile this service will not work.


2. You need the device IMEI


3. You need to verify the carrier & verify the device is "clean" or NOT on the blacklist (device has to be in clean/or clear status to unlock). If the device is on the blacklist as lost/stolen, you need to perform an "unbarring" service AKA IMEI Repair or IMEI cleaning service to get it back in clean/clear status, then you can get the unlock code. The device will get rejected and return you no unlock code if the device is blacklisted. See our IMEI Repair section if an unbarring service is needed.


4. Go to the Direct Codes unlock server. Most all servers on the Approved Unlock Server List will perform these services but our recommended unlock server for this specific service is Direct Codes.


5. While in Direct Codes Server, run a "Samsung Network Finder" service to find the original carrier.



Direct Codes - Samsung Network Finder
Direct Codes - Samsung Network Finder


6. Once you get the results from the Samsung Network Finder service, go submit the device IMEI on a carrier lost / clean / eligibility check service. This specific service will tap into the carrier servers of the specific device to make sure it is not blacklisted so you can get your unlock code. 



Direct Codes - Network Check


7. If device is clean from the results go to the "Samsung Worldwide Z Fold 6 / Flip 6 NCK + MCK Unlock Code Service" and submit the device IMEI and in a couple days you will get both the Network Unlock Code (NCK) and the MCK code. NCK is for unlocking and MCK is the DeFreeze code if you try too many attempts and get locked out of the device. The MCK code will unfreeze the device. 


8. Delivery Time: 1 - 3 Days

This service will unlock your device for worldwide use even if you are still making payments on the device (financed). Your Carrier will not unlock your device if you are on a payment plan. Our service is the only way to get your device factory unlocked for worldwide use while making payments to your carrier on your device.


You will need to supply your IMEI number (IMEI 1 or IMEI 2). Either IMEI submitted will unlock the IMEI submitted and the other IMEI, both physical SIM & eSIM. This service will provide you with the Unlock Code. You will be notified via email once the unlock code is processed and generated.

Factory resets and updates are ok, it will be sim unlocked for life.

This service provides the Unlock Code from a Samsung & carrier server database. This service is not like other Samsung Unlocking services, this is the most stable service you will find on the internet.


What is an IMEI number & where is it located?

The International Mobile Equipment Identity (IMEI) number is a unique identification or serial number that all mobile phones and smartphones have. It is normally 15 digits long. All iPhone and Android devices have an IMEI 1 and some have an IMEI 2. IMEI 1 is the physical sim tray slot and IMEI 2 is reserved for the Esim. We only need IMEI 1 to network unlock the device. Unlocking IMEI 1 will also unlock IMEI 2 (Esim) as well.


To find the IMEI on your Samsung

Go to Settings > About Phone -> Find the IMEI

Open the sim card tray and the IMEI number should be printed on the back side of the physical sim card tray

Look on the original box of the device

*The estimated time frame of service is just that, an estimated, average time of service or completion. We are fairly accurate although some services can be completed faster than our estimated time frame and some could take longer than the average time frame. It is not a guaranteed time of completion. If the service is still processing we cannot cancel. It is an auto API server. When ordered, the service automatically places the order via our unlocking server and cannot be cancelled. It is completed when the auto API service comes back as "completed" (unlocked) or "rejected" (not unlocked). We only provide refunds for rejected services.
