This means that device sends messages using modem1 > modem2 > modem1 > modem2, etc.

(see below) modem2 will be always used as a backup in failover strategy
• SIM2 as Master modem

Enable modem failover mechanism
If this setting is enabled, when one modem stops working other will automatically take over his job. This
feature requires at least two active SIM cards in the device. The health check for each modem is performed
with 3 minutes frequency. If during a health check a modem is not connected to network the other will
automatically take over his jobs (including messages waiting in Outbox folder).
