We built BrilliSIM because travel data should not be complicated

We are travelers ourselves, and we have dealt with airport SIM queues, overpriced tourist bundles, and roaming bill shock after coming home. BrilliSIM exists to remove that friction with one simple flow: choose destination, pick plan, scan QR code, and connect when you land.

An eSIM lets you prepare before departure, keep your regular number, and avoid physical SIM swaps. We work with network partners across 150+ countries so setup stays fast and predictable wherever your trip takes you.

We are a small team based in the EU, registered in Lithuania as BrilliSIM (MB), focused on clarity and reliability. No subscriptions, no hidden fees, no unnecessary complexity—just data for your trip and support when you need it.
