3.6. PIN/PUK Code Entering
3.6.1. Three Ways of PIN Code Entering
With a common mobile telephone, you have to enter your PIN code after power-on in
order to be protected against misappropriation (of your powered-off telephone) and
misuse. With the GSM Gateway, this situation may occur after power failure. The
difference is that there is often no one to know and enter the PIN code after power
recovery. There are three ways in which to solve this situation:
a) Enable the SIM card function without PIN code entering:
This is the simplest solution, but the SIM card can be easily misused when stolen.
b) Set the automatic PIN code entering:
The
PIN code is entered during programming or after power up of the GSM Gateway as
mentioned below and stored in the memory. The PIN code is then entered automatically
after every power-on.
c) Set the manual PIN code entering:
This is the safest way, which requires manual entering of the PIN code after every power-
on. Therefore, it is usable only if power failures are very rare.
3.6.2. PIN, PUK Manual Entering
If the PIN
or PUK
tone is transmitted after picking up
the line, enter the required code using the DTMF and verify the dialling with the
key.
Example:
PIN
Entering:
PUK
Entering:
If you enter the correct code, you will hear a 2 s long tone
. If not, the PIN/PUK
tone will go on. An incorrect entering (incorrect PIN or PUK, incorrect number of digits,
unacceptable characters) makes the PIN
or PUK
tone
being transmitted repeatedly. To delete an incorrect code, press ‘#’ or hang up (before entering ‘*’,
of course).
Notes:
•
A four-digit PIN code is used in the example above. An eight-digit PIN code is used
exceptionally. The GSM Gateway supports this PIN too, but has no information on how long
the PIN should be. Therefore, it transmits the same PIN tone
for this PIN
code too.
•
The GSM Gateway does not support emergency calling without PIN code!
WARNING!!!
You have a limited number of attempts for PIN and PUK code entering.
Any repeated error in PUK entering may cause damage to the SIM card!
3.6.3. Protection against Exhausting All PIN Entering Attempts by Automatic PIN Entering
Every SIM card provides a limited number of PIN and PUK entering attempts. To avoid
exhausting of all PIN-entering attempts, as a result of repeated GSM Gateway power on/off
after SIM card replacement, for example,
the automatic PIN entering is disabled
temporarily
in case the SIM card refuses the PIN stored in the GSM Gateway memory. If the
PIN is entered manually and is correct, it is stored and the automatic entering is recovered.
