Can two SIM cards work in one modem? - AER2200 - Can-2-Sim-Cards-Work-in-1-Modem/Can-two-SIM-cards-work-in-one-modem

• Can two sim cards work in the same modem at the same time?
• Will load balance work between two sim cards and one modem?

No. Each modem has only one chipset and one set of antennas, so it can have only one SIM connected at a time.

The purpose of two SIM card slots in one modem is for failover only - if the first SIM fails or reaches a data cap, the modem will switch to using the second SIM.

• Load balance REQUIRES two separate modems with a sim card in each.
