By: Dr. Philipp Schulte For more than a decade, the automotive industry has been transforming into a software-defined ecosystem, where vehicles evolve through software updates, digital services, and continuous performance improvements. The scale of that transformation is massive. As of last year, more than 400 million connected cars are on the road globally, with connectivity quickly becoming a baseline expectation for modern vehicles. At the center of this transformation is connectivity. And with the recent finalization of the GSMAâs SGP.32 specification, the industry has reached an important inflection point in how vehicles connect to mobile networks globally. The Growing Complexity of Automotive Connectivity Modern electric and software-defined vehicles rely on constant, secure connectivity to enable OTA updates, real-time diagnostics, ADAS enhancements, infotainment, telematics, and data-driven upgrades throughout the lifecycle. The complexity of these platforms is already immense. Todayâs vehicles can contain more than 300 million lines of code and generate up to 25 gigabytes of data per hour from sensors, telematics systems, and in-vehicle applications³. As automakers expand globally, this creates a logistical challenge: mobile network operator (MNO) requirements vary by country and region. Historically, supporting multiple markets often meant different hardware configurations, different SIM profiles, and region-specific integrations. That adds cost, operational overhead, and long-term rigidity â particularly for vehicles expected to remain in service for 10 years or more. What once worked for regional launches and fixed architectures no longer scales in a global, longâlived vehicle fleet. SGP.32 marks a shift from static connectivity choices to a framework where decisions can be managed, governed, and adapted over a decade or more of vehicle operation. What Makes SGP.32 Different? SGP.32 is the GSMAâs new eSIM specification designed specifically for IoT and automotive use cases. While earlier consumer-focused eSIM standards worked well for smartphones, vehicles present a fundamentally different set
