sending AT command with NCK code unlock sim? I need information. How can I send the NCK unlock code network using AT commands? Or is there any other ways?
Depends on the who made the phone and the AT command set they support.  I did this recently on a ZTE Modem using AT+ZNCK I believe, but that command isn't a standard one across all manufacturers!  Trying to do it again on an LG, no good luck so far.
