Set the default SIM

When installing two SIM cards in one modem, you can configure the default SIM to use.

You can set the default SIM by

• Set the default SIM by preferred carrier
• Set the default SIM by low cost
• Set the default SIM by SIM slot

Set the default SIM by preferred carrier

Use this option to set the default SIM if you have SIM cards from different carriers.

config extender-controller extender

edit <FEX_SN>

set authorized enable

config modem1

set ifname <fext-wan>

set default-sim carrier

set preferred-carrier <carrier name>

end

end

end

Set the default SIM by low cost

This option applies when you need to choose the low-cost SIM over a more expensive one.

You must configure two entries under “config lte plan” for the two SIM cards separately. The system will calculate the cost based on the “set capacity” and “monthly-fee”.

config extender-controller extender

edit <FEX SN>

set authorized enable

config modem1

set ifname <fext-wan>

set default-sim cost

end

end

end

Set the default SIM by SIM slot

The default SIM is sim1. You can change it to sim2 using the following commands:

config extender-controller extender

edit <FEX SN>

set authorized enable

config modem1

set ifname <fext-wan>

set default-sim sim1|2

end

end

end
