About
WassaSim is an eSIM data marketplace based in France. We let anyone purchase a data plan for 200+ countries and send it to someone they care about — in under 2 minutes.
The problem
International top-ups go through opaque channels. Roaming plans are expensive. Existing solutions require an account, an app, or understanding what an eSIM is before you can use one.
Whether it's staying in touch with family, preparing for a trip, or equipping a colleague on the road — there was no simple, fast and transparent solution.
Our solution
WassaSim sells eSIM data plans that activate instantly. The recipient receives a QR code by email, scans it, and they're connected. No physical SIM card, no store visit, no waiting.
Magic link login, order history, usage tracking, top-ups
Guest checkout, card payment, email delivery
