## Summary

Vincent Corish, CEO of Kigen, joins Memfault's Alfonso Baldasari and Chris Coleman to discuss the evolution of cellular connectivity for IoT devices, focusing on eSIM and iSIM technologies. The conversation covers the shift from physical SIMs to soldered-down secure elements, the impact of falling module costs on device design, and new business models like rental and advertising enabled by remote connectivity. Key technical topics include the GSMA SGP.32 standard for fleet management, the trade-offs between NB-IoT and LTE-M, and strategies for optimizing battery life through efficient protocol selection.
