inconsistent with the corresponding PIN code of SIM card. The SIM card will be locked.
Case 2: After the router binding function of PIN code is enabled, the SIM card is removed and placed in
another router with the same configuration for use. The
SIM card will be locked.
Case 3: After the strict encryption function of PIN code is enabled, the SIM card is removed and placed in
another router with different configuration for PIN code protection. The
SIM card will be locked.
Case 4: When the SIM card is replaced, the initial password of the SIM card is inconsistent with the initial
PIN code configured for the router. The

3. Use the PUK unlocking command with caution. The SIM card will be damaged when the number
of wrong PUK code attempts reaches 10. Before unlocking, you are recommended to first ask the
operator about the PUK code corresponding to the SIM card. PUK unlocking can also be
implemented through a mobile phone or other terminals.
Example: Configure PIN code protection (in router binding mode; the configuration for other modes is similar).

1.3 Examples of Typical Configuration
1.3.1 Disaster Recovery Scenario of Wired Link and Single 4G Link
1.3.1.1 Network requirements
The scenario involves the wired link and single 4G link disaster recovery. The wired link is used during normal
operations. After communication of the wired link is interrupted, the device can automatically detect and then enable
the 4G link. The 4G link is disconnected automatically after the wired link is recovered.
