How It Works

Traveler browses plans by country or region, filters by data, duration, and coverage type

Checks out via Stripe with Apple Pay, Google Pay, or card

System allocates a clean eSIM from the inventory pool, skipping SIMs with leftover packages

Provisioning API activates the selected plan on the allocated SIM

QR code and activation details delivered instantly with step-by-step install guide

User tracks real-time data usage on their My eSIMs dashboard
