SIM Card Handling
Your Iridium equipment monitors the SIM card status. The status
information is shown in the display of each handset in idle state.
SIM Card Messages
As long as one of the following messages are seen in the display,
the SIM card currently inserted in the RTU cannot be used for
making external outgoing calls.
• SIM card blocked: This message indicates that a wrong pin
code has been entered three times in a row with the current SIM
card inserted into the transceiver. To unblock the SIM card, enter
the correct PUK1 code.
• Card blocked permanently: This message indicates that a
wrong PUK1 code has been entered ten times in a row. The SIM
card is now permanently blocked and cannot be unblocked.
• Check SIM card: This message indicates that your Iridium
equipment has detected that some item has been inserted into
the SIM card slot. It has not, however, recognized this item as a
SIM card.
• SIM card defective: This message indicates that your Iridium
equipment has detected that a SIM card has been inserted into
the SIM card slot. For some reason, however, the Iridium
equipment cannot communicate with the SIM card.
• SIM card validation: This message indicates that a valid SIM
card has been inserted into the SIM card slot, and that the pin
code just entered is being validated by the Iridium system.
NOTE: The following features for sim card handling are only
available with RTU software version 3.0.0 and higher.
Enabling and Disabling PIN Codes
Each SIM card has an associated PIN code. In order to prevent
unauthorized use of SIM cards, your Iridium equipment is capable of
enabling and disabling the associated PIN codes.
When the PIN code from a given SIM card is enabled, the user must
enter the current value of this PIN code each time the SIM card is re-
entered into the SIM card holder in the RTU. When the PIN code for
a given SIM card is disabled, the SIM card can be used for making
external outgoing calls, provided that it is not defect or blocked.
Enabling the PIN Code

2. Find the “System” item using:
