Simfree required a seamless, cross-platform eSIM solution that allows users to activate and manage eSIMs for multiple devices effortlessly. The goal was to create a fast, intuitive, and scalable platform to cater to both individual users and enterprise clients globally.
The core idea was to simplify digital connectivity by giving users control over their eSIMs anytime, anywhere.
Users can activate, deactivate, and switch eSIMs across multiple devices without physical SIM cards.
A synchronized experience across web and mobile apps, enabling users to manage eSIMs on the go.
Users can track usage, data limits, and subscriptions in real time for better control.
The platform needed to handle growing user numbers and support multiple carriers worldwide.
The idea was to reimagine how digital connectivity works, providing both simplicity for users and flexibility for enterprises.
We began with a structured plan to ensure smooth execution across all platforms.
This planning phase allowed us to align with Simfree’s vision and ensure a smooth rollout of both web and mobile experiences.
Our workflow combined agile methodology with continuous collaboration.
Discovery & Analysis – Understanding Simfree’s goals, users, and market requirements.
Wireframing & Prototyping – Designing user journeys for both web and mobile platforms.
Development Sprints – Iterative builds for React web, React Native mobile app, and Node.js backend API.
Testing & QA – Ensuring functionality, speed, and cross-device consistency.
Deployment & Launch – Rolling out a synchronized web and mobile experience.
Post-Launch Feedback – Continuous monitoring, updates, and enhancements based on user input.
The workflow ensured the project was delivered on time, while maintaining quality and a seamless user experience across devices.
Building a global eSIM platform involved several technical and user-experience challenges:
Carrier Integration
Working with multiple telecom providers worldwide required seamless integration without interrupting user services.
Cross-Platform Consistency
Maintaining identical functionality and UX on both web and mobile apps.
Real-Time Updates
Providing instant activation, deactivation, and subscription tracking for users.
Scalability
Ensuring the system could support increasing users globally without performance issues.
Security & Data Privacy
Protecting sensitive user data and eSIM information in compliance with international standards.
Closing Note
By addressing these challenges, we delivered a robust, secure, and globally scalable platform that exceeded client expectations.
We implemented a multi-platform solution tailored to Simfree’s requirements:
React + Next.js with Tailwind CSS and Node.js backend provided a fast, responsive, and modern website for eSIM management.
React Native app with Node.js backend API allowed users to manage eSIMs across devices with real-time updates.
Centralized data storage for subscriptions, usage, and analytics, enabling real-time access and scalability.
Interactive dashboards to monitor usage, subscriptions, and performance.
These solutions created a seamless, end-to-end eSIM ecosystem for users, providing simplicity, speed, and reliability.
Our approach focused on collaboration, speed, and user experience:
Iterative sprints allowed for quick adjustments and incremental releases.
Designs focused on simplicity and ease of navigation across platforms.
React, Next.js, Node.js, and Firebase ensured the platform could grow globally.
Regular client reviews and testing ensured alignment with business goals and user needs.
This approach delivered a future-ready eSIM solution that was both scalable and user-friendly.
The tech stack was chosen for performance, scalability, and real-time functionality:
Website: React, Next.js, JavaScript, Tailwind CSS, Node.js
App: React Native, Node.js backend (API), JavaScript/TypeScript
Database: Firebase
This combination enabled a fast, responsive, and globally accessible platform for web and mobile users alike.
The platform successfully launched with measurable business and user outcomes:
Post-launch, Digital Pylot continues to support Simfree with updates, bug fixes, and performance monitoring. Our team ensures the platform remains secure, up-to-date, and fully functional, adapting to new carrier integrations and feature enhancements as the platform grows.
