Campbell Scientific 9522B Iridium Satellite Modem and COM9522B Interface Modem - Manual (Page 37)

Appendix C. Unlocking a SIM Card
There are two methods to unlock a SIM card. The equipment you have
available will dictate which method is used.
C.1 Handset Method
To unlock the Iridium SIM card permanently using the Iridium Handset, follow
these instructions.
Install the SIM card. Attach the antenna and 9522B interface. Attach the
handset as required. Apply power to the modem.
The handset will request the PIN number before proceeding. Once you enter
the PIN number (default 1111), the modem will register itself. You will need
to navigate the menus of the handset as follows:
• Find “PHONE SETUP”, click ok
• From this menu select “REQUIRE SIM PIN”
• Navigate until “OFF” is displayed, select by clicking ok
• Exit out of the menus once the PIN requirement is deactivated.
With the card unlocked, you can continue with your modem setup.
C.2 DevConfig Method
In order to unlock the SIM cards with this method, you will need DevConfig or
a terminal emulator. The configuration will need to be the same as listed in
Section 3.2, Setup of Iridium Modems. Refer to Section 3.2 for this setup.
Both SIM cards must be unlocked.
When conducting these steps, you will need to have the SIM card installed in
the modem. The antenna must be connected and have a sky view for
communication with the satellite network. Finally, the unit must be powered.
Refer to the appropriate sections of this manual for information about these
requirements.
Once the modem and DevConfig are ready, enter the following command:
AT+CPIN?
This command requests that the modem respond as to whether a password is
required. The expected modem response is:
+CPIN: SIM PIN
The response confirms that the SIM Card PIN1 code is required to unlock the
card. If you get a different response, contact the SIM card provider to
determine if a different code is required. If you get a response of “ +CPIN:
SIM PIN2”, this may mean that the card is already unlocked or requires a
different code.
