Unlocking instruction for Samsung i997 Infuse 4G ?

How to enter a network unlock code in a Samsung i997 Infuse 4G

Entering the unlock code in a Samsung i997 Infuse 4G is very simple.
1. Start the Samsung i997 Infuse 4G 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 i997 Infuse 4G 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 i997 Infuse 4G 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 i997 Infuse 4G 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 i997 Infuse 4G 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 i997 Infuse 4G 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.

Samsung i997 Infuse 4G 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 i997 Infuse 4G 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.
