FAQs
eSIM is a digital SIM technology that allows users to activate mobile plans without a physical SIM card. As major OEMs like Apple have already removed SIM trays in many markets, operators must offer eSIM to avoid churn and meet customer expectations for instant, fully digital activation.
ES is essential for enabling key eSIM use cases: seamless subscription transfers when users upgrade devices, activation of companion devices like smartwatches and iPads, and many other features. Apple requires ES for these processes, and our solution is also GSMA-compliant to support Google, Samsung, Microsoft, and more.
As a telecom operator ourselves, we built solutions we use daily. Our RSP goes beyond baseline GSMA specs for flexibility and advanced onboarding. Our ES processes device communications internally, shielding your CRM from complexity and making integration faster and simpler.
With our pre-built, operator-friendly architecture, integration can be completed in weeks, minimizing disruption to existing systems.
Yes, both our RSP and ES are fully GSMA-compliant, ensuring compatibility with all major OEMs including Apple, Google, Samsung, and Microsoft.
