Set the default SIM

When installing two SIM cards in one modem, you can set 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 lte setting
  config modem1
      set default-sim by-carrier
      set preferred-carrier <carrier name>
    end
  next
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 lte setting
  config modem1
      set default-sim by-cost
    end
  next
end

Set the default SIM by SIM slot

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

config lte setting
  config modem1
      set default-sim sim1|sim2
    end
  next
end
