Cellular WAN Settings
MLB-G420X supports Dual-SIM for cellular connection redundancy.
Redundant:
With Disable, SIM 1 is the only activate SIM interface;
With Enable, the selected SIM # interface in the priority SIM menu would be the main one. The other SIM
interface would be the backup one.
Priority SIM:
Set main SIM & backup SIM. .
Register to Network Timeout:
Default value is 5 mins (1~100).
The registration process has to be completed to a base station before the timeout specified in the Register
to network timeout field. For instance; if MLB-G420X
’s 1st priority SIM failed to register to the base station
within that time period, it changes to 2nd priority SIM.
Data Session Retry Count:
Sometimes the cellular connection is terminated based on your ISP; in such scenarios, MLB-G420X
’s
main SIM retries to reconnect the number of times specified in the data Session Retry field. If still failed, it
will change to the backup SIM interface.
Default Value is 2 (0~9999, 9999 means unlimited)
Terminated Redundant:
Under the conditions of either Register to network failed or Data session retry failed would trigger the SIM
redundant function, the redundant times such as changing from SIM1 to SIM2 or from SIM2 to SIM1 varies
from 1 to 9999 (9999 means unlimited). After the number of redundant changes reached the specified
times such as the default value is 10 times, the redundant function would be stopped.
