  • おおよそ4日程度でコードが送られてきました。 もちろんロック解除でき、非常にありがたいです。 欲を言えば、もう少し早くコードが得られると非常にうれしいです。

Network unlock code or Sim pin network code is a special type of code which removes the network blockade from your Sony Xperia Z Ultra.
These messages will appear on the screen of your Sony Xperia Z Ultra when you insert an unaccepted simcard.
Sony Xperia Z Ultra has a limited amount of unlocking attempts. Usually all Sony Xperia Z Ultra have 5 tries. If your Sony Xperia Z Ultra has a blocked code counter, there are no tries left, you cannot unlock this device by code.
Important !!! Sony Xperia Z Ultra 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.

Sony Xperia Z Ultra 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 Z Ultra usually asks for this code as soon as you insert an unaccepted simcard ( from a different network ).

It succeeded in unlock. However, it is somewhat too long for six days. I hope increasingly that it can be given early to a slight degree.
