When we think about unlocking a smartphone, we think that it is just one blockade.<BR><BR>

Unfortunately the truth is different and there are more than one blockade on a phone.<BR><BR>

The sim blockade can be made by a main network or a subnetwork.<BR>
For example Unlock your Huawei G7300 by code - unlock4huawei.com - unlock your phone is locked by O2 UK, so the main network. Now lets say that Unlock your Huawei Ascend by code - unlock4huawei.com - unlock your phone is locked by tesco, which means thatit is locked by subnetwork.<BR><BR>

Both codes can be unlocked by using the same service Unlock your Huawei Ascend by code - unlock4huawei.com - unlock your phone, but a different code will unlock a different blockade.<BR><BR>

That is why our customers recieve from one to four unlock codes.<BR>
There is no need to enter all of them, but it is always better to give all the available codes.<BR><BR>

For example Buy unlock code for Samsung Galaxy S4 now - unlock4samsung.com - unlock your phone, will receive all four codes.<BR>

Because it might be locked in a main network, subnetwork, or needs a code counter reset><BR><BR>

For unlocking a main network we use the NCK/Network code, the subnetwork unlocks by using, SPCK or NSCK code, and the code counter is used for reseting the code counter.<BR><BR>
