successfully, or the PIN authentication is 
disabled. 
  PIN code is required. 
  Enter PIN code “0000”. 
  PUK code is required. 
Remarks 
The Read command is to get the information about whether PIN or PUK code is required. 
The Write command is to set the PIN code for authentication. 
[PIN] is a string for the PIN code, [New_PIN] is a string for the new PIN code, and [PUK] is a 
string for the PUK code.   
  PIN (Personal Identity Number) is a 4~8 digit access code which can be used to secure your 
SIM card from use. If the wrong PIN is entered in more than three times, the SIM card will be 
locked. 
  PUK (Personal Unblocking Key) is an 8-digit code used to unlock the PIN code if your SIM card 
is blocked. Contact your service provider for PUK. If the wrong PUK is entered ten times in a 
row, the device will become permanently blocked and unrecoverable, requiring a new SIM 
card.
