Challenge
The aim of creating the eSIMzero app was to transform connectivity across the globe, benefiting not only individual travellers, but also businesses and corporate events alike. The existing solutions failed to offer seamless Shopify integration, lacked features for comprehensive eSIM management, and did not support the innovative concept of eSIM sharing.
The app needed to be versatile enough to cater to the dynamic needs of businesses,facilitating global connectivity, alongside offering an intuitive experience for purchasing, managing, and sharing eSIMs globally

Koroutine has brought eSIMZero to life. They've been able to understand the vision of eSIMzero and deliver a high-quality app and online shopping experience.


Solution
To address the connectivity needs of both individual travellers and businesses, we designed and developed a comprehensive mobile application using Flutter for cross-platform compatibility, and Firebase for backend support. This strategic combination ensures a consistent user experience across iOS and Android, whilst Firebase provides the scalability needed for managing eSIMs and user data securely. The app facilitates eSIM purchases, management and sharing, alongside specialised features for businesses. making global connectivity effortless and efficient for all users.
