How to Pave the Way to Manageable Global IoT Deployments with Multi-IMSI SIMs

The article introduces the cellular complexity challenge in IoT deployments, where complexity arises from multiple layers of technology and carrier interoperability. It highlights the limitations of roaming SIMs and eSIMs in addressing this challenge, with both approaches having drawbacks such as lack of control over network behavior, high latency, and increased costs. In contrast, multi-IMSI SIMs offer a solution by storing multiple IMSIs and automatically switching between them based on location, providing a more manageable and maintainable deployment option for IoT products. The article concludes that multi-IMSI SIMs are the best option for reliable global cellular connectivity, citing Twilio's Super SIM as an example of this technology in practice.
