Episode Description

In EP06 of IoT SIMple Bites, hosts Mia and David unpack SGP.32 — the key to unlocking eSIM at IoT scale. The episode traces the legacy baggage of SGP.02 and SGP.22, the three breakthroughs behind SGP.32 (bidirectional triggering, lightweight eIM+IPA, IP-based transport), the market data behind 18.6 billion IoT connections, the role of cellular modules and iSIM, security considerations, the "permanent roaming" challenge, application scenarios across automotive, agriculture, logistics, and smart cities, and practical selection advice for the road ahead. An end-to-end briefing on the eSIM roadmap for anyone building IoT.
