The Challenge
The project faced several technical and operational challenges driven by its global scale and hybrid business model. Delivering instant eSIM activation required real-time QR code generation and reliable integrations with numerous international eSIM providers across 200+ countries. Additionally, the platform needed to process multi-currency payments and support a hybrid catalog that included both digital eSIM plans and physical electronics. These requirements demanded a highly flexible, decoupled system capable of scaling efficiently, as tightly coupled architectures would limit performance, speed of iteration, and global expansion.
