Unlocking instruction for Samsung Galaxy Tab 4 ?

How to enter a network unlock code in a Samsung Galaxy Tab 4

Entering the unlock code in a Samsung Galaxy Tab 4 is very simple.
1. Start the Samsung Galaxy Tab 4 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 Tab 4 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 Tab 4 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 Tab 4 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 Tab 4 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 Tab 4 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 a message ( sim network unlock pin ) appears on the LCD of your Samsung Galaxy Tab 4, 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.

Phone freeze is a result of the incorrect code being inputted too many times, which means your Samsung Galaxy Tab 4 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 Tab 4. One of them is called unfreeze code, which is used to reset the code counter in your device. Samsung Galaxy Tab 4 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 Tab 4 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.

Unbelievable quick service, I struggled with Vodafone UK for 2 weeks playing email ping pong. Decided to give this a try, received a confirmation email within 6 hours with the unlock code, worked flawlessly.

Wysmienity serwis za kazdym razem - szczegolnie kontak z firma. Na zapytanie otrzymalem odpowiedz po kilku godzinach (minutach) tego samego dnia. Na kod do TAB4 (Tmobile) nalezy czekac do 5 dni - warto, polecam Wielkie dzieki
