What Is a Multi-IMSI SIM Card?

A multi-IMSI SIM stores multiple International Mobile Subscriber Identity numbers on a single physical SIM. Each IMSI is associated with a different mobile network operator. The SIM automatically connects to the network with the strongest signal at the device location.

Multi-IMSI SIMs are the most resilient cellular connectivity option for IoT deployments. Devices cannot be manually reconfigured in the field, so eliminating network dependency at the hardware level is critical.
