Network unlock code or Sim pin network code is a special type of code which removes the network blockade from your Sony 502SO.
These messages will appear on the screen of your Sony 502SO when you insert an unaccepted simcard.
Sony 502SO has a limited amount of unlocking attempts. Usually all Sony 502SO have 5 tries. If your Sony 502SO has a blocked code counter, there are no tries left, you cannot unlock this device by code.
Important !!! Sony 502SO 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 502SO 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 502SO usually asks for this code as soon as you insert an unaccepted simcard ( from a different network ).
