PIN Code Protection
This function sets a password for a SIM card to prevent unauthorized users from using the SIM card. The PIN code
of the SIM card is 1234 by default. Three PIN code protection modes are available, with the differences as follows:
Command Use Differences Scenario
simple Simple PIN code protection mode:
The user needs to use the CLI command to
enter the current PIN code of the SIM card. If
the PIN code is correct, the simple PIN code
protection function is enabled; if the PIN code
is wrong, the SIM card cannot be used, and
PUK unlocking is needed (for details, refer to
operation of the PUK unlocking scenario).
Use the NO command to disable the simple
PIN code mode. The numeric string
entered by the user is
the PIN code
corresponding to the SIM
card. This PIN code is
visible to the PIN code
administrator and the
security level is low. The SIM card can be
inserted into a router or
mobile phone terminal
supporting the PIN code
input function.
strict-pin Strict PIN code protection mode:
The user needs to use the CLI command to
enter the current PIN code of the SIM card
and a HASH string. If the PIN code is correct,
the strict PIN code protection function is
enabled and the HASH string will replace the
current PIN code; if the PIN code is wrong,
the SIM card cannot be used, and PUK
unlocking is needed (for details, refer to
operation of the PUK unlocking scenario). A new PIN code is
obtained after the
numeric string entered
by the user is hashed.
The new PIN code is
invisible to the PIN code
administrator and the
security level is high. The SIM card can only be
inserted into Qtech router
for use.
bind-router Binding the router PIN code protection mode:
The user needs to use the CLI command to
enter the current PIN code of the SIM card
and a HASH string. If the PIN code is correct,
the PIN code binding protection function is
enabled and the current PIN code is replaced
after hashing using the router serial number;
if the PIN code is wrong, the SIM card cannot
be used, and PUK unlocking is needed (for
details, refer to operation of the PUK
unlocking scenario). A new PIN code is
obtained after the router
serial number is hashed.
This PIN code is directly
bound with the router
and the security level is
highest. The SIM card can only be
used on a fixed router of
Qtech.
