14.5 PIN
Any device is protected with a PIN (Personal Identification Number).
This PIN must be specified entering some commands and opening a configuration session.
Default factory PIN
0000
can be modified by means of GsmSuite or specific SMS sent by
supervisors:
+2,297,,PIN,,,,,,NUMBER
14.5.1 Operating without SIM PIN
The simplest way is to put your SIM card into a cellular phone and program it so it won't ask for
the PIN. The SIM card is 'open' and someone could steal the SIM card, use it and read the
information inside.
14.5.2 Enter default SIM PIN
Since any device is factory set to a default PIN = 0000 (four zeroes), put your SIM card into a
cellular phone and program the PIN using this default number.
14.5.3 Change default SIM PIN
Of course, maximum protection is achieved when default PIN is changed to a new one and kept
secret. Using GsmSuite device and SIM PIN will be aligned, when the editing of index 297 is
made by SMS, put your SIM card into a cellular phone and program the PIN using the new
stored number .
Common PIN are 4 characters long.
This device can anyway handle also long PIN (8 characters).
14.5.4 WARNING
If you insert a SIM card that asks for a PIN number different from that stored into the unit, this
will not operate. Turning on the device 3 times having mismatch condition, SIM card will lock up
and you must provide the PUK (PIN Unblocking Key).
14.5.5 Example
+2,297,,PIN,,,,,,1234
Set new device PIN to 1234, this will not affect the SIM card.
14.5.6 Confirmation
Once Phonebook edit has been successfully done, device will send back an SMS specifying
assigned index, name and 7 markers to specify which fields are defined (*) and which don’t (-):
297,PIN,------*
