Challenge
Pearky Inc., a UK-based travel-tech startup, approached Apptechies with the vision of creating a global travel eSIM app that would make international connectivity simpler, faster, and more affordable. The challenge was to build a lightweight, user-friendly mobile application that could handle eSIM data plan browsing, purchasing, installation, and management for over 200 countries and regions. It also needed to support secure payments via multiple global gateways and work smoothly across iOS and Android devices. Integrating real-time plan activation, dual-SIM support, and secure onboarding—while maintaining a seamless user experience—was a complex task. The app had to ensure data privacy, instant eSIM provisioning, and uninterrupted performance for users on the move.

Solution
Apptechies designed and developed Pearky, a next-generation mobile eSIM application built using Flutter for cross-platform performance. Our team used Node.js for backend services and integrated Firebase for authentication and real-time updates. The app supports in-app purchases with Visa, Mastercard, PayPal, Apple Pay, and Google Pay, offering travelers maximum flexibility. We created an intuitive eSIM marketplace where users can browse plans by country or region, complete secure transactions, and install eSIMs through a guided setup process. The app features dual-SIM functionality, allowing users to use data via eSIM while keeping their physical SIM active for calls. With a clean and minimal UI/UX, Pearky ensures smooth navigation, fast performance, and easy onboarding, even for first-time users.
