What matters

We prefer Fly eSIM

We prefer Fly eSIM

Fly eSIM covers more of the live catalog or starts cheaper on the same scale. Billion Connect can still win a specific trip if the destination sheet says so.

Open Billion Connect when the destination page shows a clearer network, hotspot rule or price for that itinerary. Do not crown a winner from the homepage.

Questions

Billion Connect vs Fly eSIM 2026: Compare eSIM prices+

Fly eSIM covers more of the live catalog or starts cheaper on the same scale. Billion Connect can still win a specific trip if the destination sheet says so.

When does Billion Connect make sense?+

Billion Connect is easiest when you want purchase, install and top-up in one place. Hong Kong prepaid packs, QR or the BC eSIM app, with a 128 kbps fallback. In our current sample: 1,745 priced plans across 99 destinations, median EUR 1.08/GB on limited packs. A polished app says nothing about the local radio network.

Do you give this provider a score?+

No. We do not publish a customer rating or a best-provider badge. This page shows normalized catalog fields — price, data, validity, coverage, 5G and hotspot — plus sourced product notes. A commission on an outbound link does not change those numbers.
