5.2 AT+CPIN2 PIN2 Authentication
Description: AT+CPIN2 controls network authentication of the Multi-Tech wireless modem.
The read command returns an alphanumeric string indicating whether or not network
authentication is required.
The write command allows the Multi-Tech wireless modem to store the entered password. This
may be, for example, the SIM PIN2 to benefit from the features listed below or the SIM PUK2
to replace a disabled PIN2 with a new one. Note that PIN2 can only be entered if PIN1
authentication was done.
If the device is requesting SIM PUK2, use <pin> to enter the PUK2, followed by <new pin> to
specify the new PIN2.
Syntax: Test Command: AT+CPIN2=?
Response: OK
Read Command: AT+CPIN2?
Response: +CPIN2: <code>
OK
ERROR
+CME ERROR: <err>
Write Command: AT+CPIN2=<pin>[, <new pin>]
Response: OK
ERROR
+CME ERROR: <err>
Parameters:
<pin> Password (string type), usually SIM PIN2 or, if requested, SIM PUK2.
<new pin> If the requested code was SIM PUK2: new password (PIN2).
See Section 5.1.1, What to do if PIN or password authentication fails? for
more information about when you may need to enter the PUK.
<code>
READY ME is not pending for any password.
SIM PIN2 ME is waiting for SIM PIN2. This <code> is returned only when
PIN2 authentication has not yet been done or has failed
(“+CME ERROR:17”).
SIM PUK2 ME is waiting for SIM PUK2. This <code> is returned only
when PIN2 authentication has failed and ME is pending for
SIM PUK2 (i.e., “+CME ERROR:18”).
Notes:
• Functions accessible only after PIN2 authentication:
AT+CACM: Accumulated call meter (ACM) reset or query
AT+CAMM: Accumulated call meter maximum (ACMmax) set or query
AT+CLCK: Facility lock to “FD” (Fixed dialing phonebook)
AT^SLCK: Facility lock to “FD” (Fixed dialing phonebook)
AT+CPWD: Change “P2”password
AT^SPWD: Change “P2”password
AT+CPUC: Price per unit and currency table
AT+CPIN2: Enter SIM PIN2 or SIM PUK2 if requested.
For example, SIM PIN2 will be needed when you attempt to edit the “FD” phonebook and ME returns “+CME
Error 17” or “+CPIN: SIM PIN2”.
Once the required <pin> has been entered correctly, PIN2 authentication code changes to READY. After
300s, a repetition of the authentication process is required; PIN2 authentication code changes from READY
to SIM PIN2.
• This command is PIN protected.
• This command is supported in airplane mode.
