Unlocking instruction for Samsung Galaxy S4 Active ?

How to enter a network unlock code in a Samsung Galaxy S4 Active

Entering the unlock code in a Samsung Galaxy S4 Active is very simple.
1. Start the Samsung Galaxy S4 Active 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 S4 Active 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 S4 Active 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 S4 Active 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 S4 Active 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 S4 Active 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 S4 Active, please use this link:
Samsung network unlock.
If a message ( sim network unlock pin ) appears on the LCD of your Samsung Galaxy S4 Active, 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 S4 Active
Phone freeze is a result of the incorrect code being inputted too many times, which means your Samsung Galaxy S4 Active 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 S4 Active. One of them is called unfreeze code, which is used to reset the code counter in your device. Samsung Galaxy S4 Active 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 S4 Active 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.

This is working perfectly, thanks Expected it to take 5 days, got the code after 10mins Five stars from me Best Regards Thomas

2014-10-09 22:23:10 Josh

This service is completely legitimate. I was initially very dubious based on the number of scam websites I found. This is not a scam. My phone — which was still on contract with AT&T — was successfully unlocked using the first code provided. Well worth the money (AT&T refused to unlock the phone). Took six days to get the unlock code, but worth the wait.

2014-09-12 03:33:35 Felix

I received the code 7 days after it was ordered. As I was in no rush, it was okay. I unlocked the phone without any problems. I suppose the best way to improve the service is to deliver the code more quickly. Perhaps within hours after payment.
