Enabling PIN Code Protection
Command
Description
Qtech# configure terminal
Enters the global configuration mode.
Qtech(config)# interface cellular 0/0
Enters the interface configuration mode.
Qtech(config-if-Cellular 1)# plmn pin-protection simple 0
1234
Enables the simple PIN code protection function. The
last numeric string in configuration is the PIN code
corresponding to the SIM card.
Qtech(config-if-Cellular 1)# plmn pin-protection bind-router
0 1234
Enables the PIN code protection function of router
binding mode. The last numeric string in configuration is
the PIN code corresponding to the SIM card.
Qtech(config-if-Cellular 1)# plmn pin-protection strct-pin
12345678 0 1234
Enables the strictly encrypted PIN code protection
function. The last numeric string in configuration is the
PIN code corresponding to the SIM card. The first
character string is a strictly encrypted hash string.
1. When a 3G card and the corresponding SIM card are inserted for the first time, the initial
password of the SIM card is known by the customer. The password is 1234 by default if it was not
changed before.
2. The router administrator enables the PIN code protection function through CLI. When this
command is enabled, enter the correct initial PIN code of the SIM card. If the PIN code is wrong. The
SIM card will be locked. PUK unlocking is needed. Refer to scenario 1 of PUK unlocking.
3. When the router is bound or the strict encryption mode is enabled, the PIN code has been
encrypted and is not the original PIN code 1234 any more, and 1234 cannot be used on other
devices (such as a mobile phone) to enable the PIN code protection function. Only the
no plmn pin-
protection
command can be used on this router to disable the PIN code protection function.
4. In router binding or strict encryption mode, the new PIN code is encrypted for saving and invisible
to the administrator.
5. Each time when the SIM card connects to the network in dial-up connection mode, the router will
use the new PIN code to unlock the SIM card. If the PIN code is correct, normal dialing can be
implemented and the SIM card can be used to access the network normally.
6. The three modes use the same command to cancel the PIN code protection:
no plmn pin-
protection
. This command can be executed only when the PIN code protection command is
executed.
7. The SIM card is relocated from router A to router B, router B has been configured with the PIN
code protection related command, and a new PIN code is available. There are
two cases
for SIM
card replacement:
Case 1: If the PIN code of SIM card is consistent with the PIN code for the CLI command of router B, the
related process is the same as the initial use process. The code can be replaced directly for use. The
router first uses the initial password to enable PIN code protection. After the function is enabled, a new
PIN code is generated according to the binding or strict encryption algorithm. After that, the router will use
the new PIN code to unlock the SIM card each time the 3G card connects to the 3G network in dial-up
connection mode. If the PIN code is correct, normal dialing can be implemented and the 3G card can be
used to access the network normally.
Case 2: If the PIN code of the SIM card inconsistent with the PIN code for the CLI command of router B,
directly replacement may lead to locking of the SIM card. In this case, a designated administrator needs to
unlock the SIM card by using the PUK code, and then reset the PIN code (for details, refer to the section
about PUK unlocking).
Case 2 above can be handled by using the following three methods:
①
: Before replacing the SIM card, use another device (such as a mobile phone) to change the PIN code
of SIM card to the initial PIN code configured on the router, and then insert the card into the router
for use;
②
: Before replacing the SIM card, delete router configuration, insert the new card, and then configure the
PIN protection function again;
