SIM PIN
SIM (Subscriber Identification Module) is a smart card containing all subscriber specific data stored in it. A default
Personal Identification Number (PIN) is also stored in the SIM. SIM PIN is a security feature used by the GSM
network. SE is recommended to enable SIM protection to protect the SIM card.
How SIM PIN protection works?
• At every Power On, the module will send SIM PIN request to the system. (If SIM protection in the SIM Card
is enabled)
• The system will send the SIM PIN stored in the configuration to the module. The GSM module gets
registered with the GSM network, if correct SIM PIN is issued.
• SIM PIN sent by the system should match the one that is stored in the SIM Card.
• If wrong SIM PIN is issued for three times then the system will ask for the Personal Unlock Keyword. PUK
number is a unique number assigned to every SIM card by the service provider.
• If the SIM Card is locked then SE must contact the service provider and get PUK number from him to
unlock the card. If wrong PUK number is entered for ten times then the SIM card will become useless.
• GSM module gets initialized only if SIM PIN of the SIM Card and that of the system matches. Hence it is
necessary that the SIM PIN of SIM Card and the one that is stored in the system is same.
To enable SIM protection or to match SIM PIN of SIM Card and the system, follow the steps given below when the
system attains normal working position:
• Switch Off GFXD1111S.
• Remove SIM card and insert the same in the mobile instrument.
• Enable 'SIM PIN at Power ON' parameter in the SIM card. (This step is not required if SIM protection is
already ON)
• Change the SIM PIN of the SIM Card to 1234. (Default SIM PIN programmed in the system is 1234)
• The SIM PIN of the card and that of the system should be same else the SIM PIN will not be accepted by
the GSM module at power on.
• Insert SIM card in GFXD1111S and switch on the system. SE is recommended to change the default SIM
PIN after GFXD1111S attains normal working position by issuing command shown in 'How to Program?'
topic below.
• When SIM PIN change command is issued after following the above steps, SIM PIN of both SIM Card and
that of the system is changed simultaneously.
• SIM PIN feature is also supported when Wavecom-CDMA (Q2438K) module is installed in SIMADO
GFXD1111S.
• SIM PIN is not defaulted or changed if the system is defaulted or software version revision is changed.
