How to enter the unlock code Samsung “Network Locked”
Some carriers in some countries apply a certain type of network lock on the phones they sell, a type of lock that, when you enter a SIM card from a different carrier, your phone will only read “Network Lock”, instead of “SIM Network Unlock PIN”, and will not have a dedicated field where to insert the code.
So basically, your Samsung will inform you that it’s network locked, but will not allow you to insert a code to unlock it.
Method 1
Go to the dial screen on your phone and, as you would make a call, please dial: #7465625638# Now your phone should prompt the message “SIM Network Unlock PIN” and you’ll have a dedicated field where to insert the code.
If this method worked, you can now place an order, as now you’ll be able to use the code you’ll receive from us.
To try the following two methods you need the network unlock code.
Method 2
Go to the dial screen on your phone and, as you would make a call, please dial: #7465625638UNLOCKCODE# Now your phone should read the message “Network unlock successful” and be permanently unlocked.
If, by using this method, you get the message “Unlock Unsuccessful” please follow this link for further instructions.
If you get another message, other than “Unlock Successful” or “Unlock Unsuccessful”, please try method 3.
Method 3
Go to the dial screen on your phone and, as you would make a call, please dial: #0111UNLOCKCODE# Now your phone should read the message “Unlock Successful” and be permanently unlocked.
If, by using this method, you get the message “Unlock Unsuccessful” please follow this link for further instructions.
How to Remove SIM Network Unlock PIN from Samsung Galaxy
If you are a proud Samsung device owner and looking for the online web solutions to unlock or to remove SIM Network Unlock PIN from your Samsung smartphone, then this article is probably of your interest.
Many of the Samsung smartphone users are facing this problem and hence they approach the Samsung Customer Care Service to resolve this issue. But we want to tell you that they won’t help you in any case because it is the part of the contract to which you had agreed when you purchased that smartphone. Many network provider operators had a deal with the Samsung Company. You will often come to see the advertisement of different network providers on the boxes of the smartphone. And in return, the manufacturing company of the smartphone will make a contract that it won’t let the user switch to another network provider. That’s why it is not possible to insert a new SIM card because your smartphone will not recognize that until the contract gets over. The SIM card gets locked to a particular company until the contact time period gets over.
But if you want to change your SIM card operator probably due to some network issues, then you can accomplish your task without any worry. In this article we will tell you about the two methods which you can use to remove the SIM network unlock PIN on Samsung Galaxy phone by inserting a new SIM card of your choice. By the way, you can also unlock Samsung phone free with IMEI number.
Please note that different versions or series of Samsung Smartphones have different steps of instructions, and we will try to cover all the possible versions so that you won’t face any problem in this task.
Method 1: Unlock Samsung SIM Network Unlock PIN by Contacting Network Carrier
In this method for Samsung Galaxy SIM unlock, you have to obtain the required PIN from the network carrier by contacting them. You will get the required PIN after the contract gets over and then you can call the network provider and ask for the unlock PIN by giving them the required information. They will check and confirm the details and after that, they will provide you a 4-digit network unlock PIN which you can use to unlock the SIM network lock. Unlocking of SIM card lock will let you insert and use the SIM card of different network provider of your choice. But before you call on the customer care, please ensure that the contract is over and there is no cheating involved. And just in case if you had purchased your Samsung smartphone on EMI transactions, then you have to pay the remaining amount to the company before you ask for the SIM network unlock PIN.
After you get the required SIM card to unlock PIN, you have to follow our instructions to make sure that your phone will recognize the insertion of the new SIM card. Just follow these instructions carefully:
- First of all, just switch off your Samsung smartphone by pressing the power key for a few seconds and then choosing the “Power Off” icon.
- After the phone gets switched off, just remove the SIM card and insert the new SIM card. After you are done with that, power on your phone by pressing the home key for few seconds again.

- After you enter the correct PIN, you unlock the SIM network lock and will be able to use your new SIM card hassle free.
In case if the official customer care service of your current network company didn’t provide you the required unlock PIN, then you can approach the Samsung customer care service. You have a right to raise the demand of the unlock PIN after the contract gets over.

But if you find yourself reading this article, you’re likely already aware of that. What you want to know is how you can SIM unlock the Samsung Galaxy S9 since it is SIM locked to your service provider. The main reason to SIM unlock the Samsung Galaxy S9 and Galaxy S9 Plus is because you’re planning to switch service providers, but a SIM-unlocked Galaxy S9 can also fetch a higher price if you’re planning on selling the phone as well. Regardless of why you need it, the instructions below will help you secure a free Samsung Galaxy S9 SIM unlock code for your device.
Keep in mind that it can take 2-3 days to get a free SIM unlock code for your device. If you can’t wait that long, you might consider picking your Samsung Galaxy S9 SIM unlock code from Android SIM Unlock or similar third-party services.
Free Samsung Galaxy S9 SIM unlock code
What many people don’t know is that getting a free SIM unlock code for the Samsung Galaxy S9 and the Galaxy S9 Plus is fairly easy. If you look through your service provider’s fine print on their website, you’ll find that most of them will give you the SIM unlock code for your phone, just as long as you meet a handful of requirements. Each service provider has their own unique requirements, but typically you’ll need to make sure that the phone you are trying to unlock is paid in full, your account is in good standing (no late or unpaid bills) and that you’ve owned the phone for 60-90 days. If you meet these requirements, you shouldn’t have any issues getting a free SIM unlock code for your Samsung Galaxy S9 or Galaxy S9 Plus.

- Open the phone app and dial #06# to display your Samsung Galaxy S9’s IMEI number
- Wrote the number down on a piece of paper for quick reference

T-Mobile Metro PCS SIM unlock
A Samsung Galaxy S9 or Galax yS9 purchased from T-Mobile or Metro PCS comes with their own unique SIM unlocking process.
