  • Page 32: Section 5 - Sim Card Specific Information

    – – The AT+CPIN command controls network authentication of the TC65. The read command (AT+CPIN?) returns an alphanumeric string indicating whether or not network authentication is required. The write command allows the modem to store the entered password. This may be for example the SIM PIN1 to register to the GSM network, or the SIM PUK1 to replace a disabled SIM PIN1 with a new one, or the PH-SIM PIN if the client has taken precautions for preventing damage in the event of loss or theft etc.

  • Page 33: What To Do If Pin Or Password Authentication Fails

    What to do if PIN or password authentication fails?
