Cellular SIM Management

Cellular SIM management in Meraki provides comprehensive configuration and failover capabilities for cellular gateway deployments. SIM management enables redundant cellular connectivity through multiple carrier relationships, automatic failover between SIM cards, and intelligent traffic routing based on connectivity quality and cost optimization. This functionality is essential for maintaining business continuity in remote locations, ensuring reliable backup connectivity, and optimizing cellular data costs across diverse deployment scenarios.

Examples

Example-1: The example below demonstrates cellular SIM configuration.

This configuration manages multiple SIM cards for redundant cellular connectivity and automatic failover capabilities. The example includes SIM card assignments, carrier settings, and failover policies for reliable cellular gateway connectivity and business continuity.

This configuration configures the cellular SIM settings for device identified by environmental variable “cellular_gateway_01”. It configures SIM failover functionality where “enabled: true” activates automatic SIM failover capability between primary and secondary SIM slots. The “timeout: 300” parameter sets the failover timeout to 300 seconds (5 minutes), meaning the MG cellular gateway will switch to the standby SIM card if it cannot establish dashboard connectivity for 5 minutes on the primary SIM. This aligns with Meraki MG documentation where auto SIM failover triggers after 5 minutes of connectivity loss.
