Unlocking the Samsung Galaxy series devices has become an increasingly common request, whether due to forgotten passwords, device malfunctions, or purchasing a used device. Fortunately, various methods exist to bypass these locks, each catering to specific circumstances. However, before embarking on this process, it’s essential to remember that unlocking a device may have legal implications depending on the context, such as lost or stolen property. Therefore, it’s crucial to proceed responsibly and ensure the proper ownership of the device.
The most straightforward approach is to use the original password or PIN set up during the initial device setup. If this method is feasible, it’s recommended as it doesn’t require any additional tools or software. However, if you’ve forgotten the credentials, alternative routes need to be considered. One option is to utilize Samsung’s Find My Mobile service, which allows the user to remotely unlock the device if they are logged in to their Samsung account. This service is accessible through a web browser and requires an internet connection.
If remote unlocking is not an option, the next step is to perform a factory reset. This will erase all data on the device, including the lock screen password. However, it’s crucial to note that a factory reset should only be considered a last resort, as it will delete any unsaved data or files. Additionally, some devices may have additional security features that prevent unauthorized factory resets, such as FRP (Factory Reset Protection), which requires the user to enter the previous Google account credentials after a reset. This feature is intended to prevent stolen devices from being unlocked without the owner’s knowledge.
Unlocking with Find My Mobile
Find My Mobile is a cloud service from Samsung that allows you to locate, lock, or unlock your device remotely. It can also be used to unlock your device if you’ve forgotten your password or PIN.
To unlock your device using Find My Mobile, you’ll need to:
- Visit the Find My Mobile website and sign in to your Samsung account.
- Select the device you want to unlock.
- Click on the “Unlock” button.
Your device will now be unlocked and you’ll be able to access it again.

- It’s a secure way to unlock your device because you need to be signed in to your Samsung account to do it.
- It’s a free service.
Using a Third-Party Service
Unlocking your Samsung Galaxy through a third-party service is another option. These services typically charge a fee, but they can be faster and more convenient than using a carrier. Here’s how to proceed with a third-party service:
1. Research and Choose a Service
Before you use any third-party service, it’s crucial to conduct thorough research and read customer reviews to ensure their credibility and reliability. Look for services with a proven track record and positive feedback from previous customers.
2. Collect Device Information
Once you’ve selected a service, you’ll need to provide them with specific information about your device, including its IMEI number, model number, and carrier information. You can usually find this information in your device’s settings or on a label on the back of the device.
3. Place Your Order and Submit Payment
After gathering the necessary device information, place your order with the third-party service. The cost of unlocking your device can vary depending on the service and the device model. Most services require you to pay online using a credit card or PayPal. Once payment is confirmed, the unlocking process will begin.
| Payment Method | Advantages | Disadvantages |
|—|—|—|
| Credit Card | Convenient and widely accepted | Requires a strong credit history |
| PayPal | Secure and protects personal information | May have lower spending limits |
| Debit Card | Directly linked to your checking account | Transaction fees may apply |
4. Wait for Network Unlock Code
Once the payment is processed, you’ll receive an email from the third-party service containing a Network Unlock Code (NUC). This code is unique to your device and will allow you to unlock it from the current carrier’s network.
5. Enter the Network Unlock Code
With the NUC in hand, you can now unlock your Samsung Galaxy. Insert a non-accepted SIM card into your device, and you’ll be prompted to enter the NUC. Input the code and follow the on-screen instructions to complete the unlocking process.
Troubleshooting Common Unlocking Issues
Issue 1: Invalid Unlock Code
Ensure that the unlock code you entered is correct. Check if you have any typos or missed characters. If unsure, contact your network provider to confirm the code.
Issue 2: Code Not Accepted
The unlock attempt may have failed because of incorrect entry attempts. Allow a buffer time before trying again. If the code is still not accepted, contact your network provider.
Issue 3: Network Lock Not Removed
After entering the unlock code, restart your device to complete the process. If the lock persists, contact your network provider to verify if the device has been fully unlocked.
Issue 4: Different Network SIM Card Rejected
Check if the network you are attempting to use is supported by your device’s hardware. Some devices may have regional network limitations. Contact your new network provider to confirm compatibility.
Issue 5: Re-Locking After Unlock
If the device re-locks itself after being unlocked, it may have been re-networked with a SIM card from the original carrier. Avoid re-inserting the original SIM card after unlocking to prevent this issue.
Issue 6: Complete Guide to Solving the “Enter Network Unlock Code” Error
Step 1: Check Your Device’s Eligibility: Not all Samsung Galaxy devices can be unlocked. Check with your carrier or network provider to confirm eligibility.
Step 2: Gather Required Information: Obtain your device’s IMEI number (dial *#06#) and contact your network provider for an unlock code.
Step 3: Enter the Unlock Code: Go to Settings > Connections > Mobile Networks > Network Unlock. Enter the unlock code and tap Unlock.
Step 4: Verify Unlock Status: Restart your device and insert a SIM card from a different network. If the device accepts the new SIM card, the unlock was successful.
Step 5: Troubleshooting Failed Unlocks: If the unlock code fails or the device remains locked, refer to the other troubleshooting steps outlined in this troubleshooting guide.
Step 6: Contacting Your Network Provider
If all other troubleshooting steps fail, contact your network provider for further assistance. Explain the issue and provide your device information. They may be able to provide additional support or investigate the issue further.
