As telcos navigate the shift from connectivity providers to digital experience platforms, eSIM emerges as the most powerful monetisation engine. Drawing from global best practices, the SHIFT framework, and 30+ operator case studies, this report highlights how operators are achieving 15% CAC reduction, 95% install success rates, 30% lower churn, and sub-3-minute onboarding — as platforms like Amazon, Starlink, and super apps race to embed connectivity invisibly into the customer journey, making the aggregator threat far broader than Airalo alone.\n\nThe study delivers the SHIFT framework and four strategic plays for operators to win, outlining how telcos can design, launch, and scale eSIM propositions from activation to market leadership. It demonstrates that eSIM is not just a connectivity upgrade but a strategic vehicle for acquisition, ARPU expansion, and B2B2X value creation — with operators achieving 85% customer awareness, 94% eKYC pass rate, 15% repeat purchase, 65% roaming utilisation — enabling operators to counter aggregator and platform threats, unlock multi-device revenues, and capture enterprise and IoT opportunity. The report delivers a structured blueprint for proposition design, go-to-market strategy, and a practical product development checklist to successfully monetise and drive digital-first goals.
