Description
eSimLab | Flutter Mobile eSim Solution
eSimLab | Flutter Mobile eSim Solution 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.
