Multi-IMSI SIM cards are the perfect fit for mission-critical IoT applications which must avoid downtime at all costs.
An IMSI (International Mobile Subscriber Identity) is assigned to one operator and therefore gives one connectivity option. This leaves you reliant on that one network.
Multi-IMSI SIM cards are provisioned with multiple IMSIs. Each of the IMSIs on our Multi-IMSI SIM operates on a completely separate network infrastructure. If there is an issue on the core or home network, the SIM automatically switches to both a better signal and a completely different architecture.
Multi-IMSI connectivity is the best fit for those applications that need multiple redundancies to avoid downtime at all costs.
