eSIM Platform is a full-stack eSIM marketplace: a Next.js web application (marketplace, admin panel, checkout) and a companion Flutter mobile app (iOS & Android). Both share the same REST API backend and PostgreSQL database, letting travelers discover, purchase, and manage eSIM data plans on web or mobile. The web handles admin operations, eSIM provider integration, and web checkout (Stripe / Lemon Squeezy); the mobile app adds native store billing (RevenueCat), Stripe, Adyen, PayPal, push notifications, and Firebase Remote Config.

Key Value Propositions

• For Travelers: Browse featured destinations and data plans, search by country or region, compare coverage and pricing, purchase instantly, scan a QR code to activate, and monitor real-time data usage — all from a single mobile app.
• For eSIM Resellers / App Owners: A ready-to-launch mobile storefront connected to the eSIM Platform backend. Sell plans via native store billing (RevenueCat), card payments (Stripe / Adyen), or PayPal — with guest checkout, account linking, order history, and push notifications built in.
• For Developers: Clean Flutter architecture with Firebase Remote Config for runtime settings, JWT auth against a REST API, 12-language localization, AdMob monetization, Meta App Events analytics, and release checklists for both stores.
