These messages will appear on the screen of your Sony Xperia Z1s when you insert an unaccepted simcard.
Sony Xperia Z1s has a limited amount of unlocking attempts. Usually all Sony Xperia Z1s have 5 tries. If your Sony Xperia Z1s has a blocked code counter, there are no tries left, you cannot unlock this device by code.
Important !!! Sony Xperia Z1s with a blocked code counter will still ask for a network unlock code.
Even if you enter the correct code it won't work with a blocked code counter.

The code counter can be reset only by an official Sony service.
Sony Xperia Z1s needs different types of unlock codes to remove the network blockade.
One of these codes is a NSCK code which is used in most Japanese networks like Docomo, Softbank etc.
Those networks cannot be unlocked with the standard NCK code.
Sony Xperia Z1s usually asks for this code as soon as you insert an unaccepted simcard ( from a different network ).
