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.

FX511FTQ21001262 # config lte setting modem1

FX511FTQ21001262 (modem1) # set default-sim

sim1

sim2

by-carrier

by-cost

FX511FTQ21001262 (modem1) # set default-sim by-carrier

FX511FTQ21001262 (modem1) <M> # set preferred-carrier

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”.

FX511FTQ21001262 # config lte setting modem1 
FX511FTQ21001262 (modem1) # set  default-sim 
sim1          
sim2          
by-carrier    
by-cost       

FX511FTQ21001262 (modem1) # set  default-sim by-cost

Set the default SIM by SIM slot

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

FX511FTQ21001262 # config lte setting modem1 
FX511FTQ21001262 (modem1) # set  default-sim 
sim1          
sim2          
by-carrier    
by-cost       

FX511FTQ21001262 (modem1) # set  default-sim sim1/sim2
