Unlocking instruction for Samsung Galaxy J3 ?

How to enter a network unlock code in a Samsung Galaxy J3

Entering the unlock code in a Samsung Galaxy J3 is very simple.
1. Start the Samsung Galaxy J3 with an unaccepted simcard (unaccepted means different than the one in which the device works)
2. Special unock window should appear
- For message Sim network unlock pin you should enter the codes if the following order, Unfreeze confirm, NCK confirm (please try a couple of times if the Galaxy J3 does not accept it for the first time)
There is also a special RGCK (regional lock code) code sometimes provided. Please use the RGCK code the same way as the NCK code.
- If Service provider pin appears enter the codes in this order
Unfreeze confirm, SPCK confirm (try a couple of times)
3. Samsung Galaxy J3 is now network unlocked !!!

* sometimes the unfreeze code is not provided by the network (check the description of chosen service)

In order to unlock Samsung Galaxy J3 network blockade, you need a NCK (network) code. If the code counter is blocked, you will need MCK (unfreeze) code as well to reset the code counter.
If Samsung Galaxy J3 has a blockade for a subnetwork like Tesco or Virgin you need to use a SPCK (service provider) code.
Most devices bought on a contract from a network provider are network blocked.
It means that the Samsung Galaxy J3 can only receive signal from one network. If you insert a simcard from a different network, the device will ask for an unlock code, or will show the message that this simcard doesn't work.
Networks that can be unlocked include: AT&T USA, Orange, EE and many more.
If you want to remove a network blokade from Samsung Galaxy J3, please use this link:
Samsung network unlock.
If a message ( sim network unlock pin ) appears on the LCD of your Samsung Galaxy J3, it means that the device is blocked. You cannot use any other network, until you enter the correct unlock code. Every network has a different price and unlocking time, but all of them can be unlocked. Use the link below to check your device Unlock networks for Samsung Galaxy J3
Phone freeze is a result of the incorrect code being inputted too many times, which means your Samsung Galaxy J3 is Hardlocked. You will require a Defreeze (MCK) code and a NCK code to unlock your phone.
There are different types of unlock codes for your Samsung Galaxy J3. One of them is called unfreeze code, which is used to reset the code counter in your device. Samsung Galaxy J3 usually have 3 TRIES to enter the unlock code. The biggest problem is that the phone doesn't show the code counter and there is no way to check. If you want to unlock a Samsung Galaxy J3 with a blocked code counter, you need the unfreeze code. The code can also be used to remove a regional blokade if you want to travel to different countries.

Received the codes about a day after I placed the order. Code worked first time. So thanks :-) I had previously tried a different website who said they couldn't do it and another that wouldn't give me the code until I'd signed up for 'special offers' no thanks. Improvements 1. could be quicker - e.g. instant 2. Cheaper £18 is a bit much. £10 would be acceptable. but, hey, you did the job as you said you would, so thanks again.

2017-11-21 21:19:09 Marc

Worked excellently. You have to be a bit fearless as far as it's quite unclear in the samsung user interface when to enter which code (Some cellphones can be bricked by wrong codes) - but it seems that the Galaxy phones are quite tolerant.

2017-11-20 16:04:19 Michael

Always a pleasant surprise when a product or service delivers what is promised. And Sim-Unlock.net delivered exactly as promised, on time, and success on first try. Definitely good value for money and 5-star result
