This document discusses different cellular connectivity options for IoT devices and how a multi-IMSI architecture makes global deployments more manageable. It explains that a multi-IMSI SIM provides access to multiple cellular networks from a single SIM card, avoiding the need to procure SIMs from multiple carriers. When combined with an eSIM, it offers the benefits of both technologies like coverage, control over network selection, and independence from vendors. The Twilio Super SIM is highlighted as a product that uses this approach to deliver maximum uptime and efficient management of global IoT fleets through a single connectivity platform.
