eSimfly does not provide a truly unlimited high‑speed data eSIM for France. The plans that carry the word “Unlimited” actually supply a fixed 3GB per day allowance; once that limit is reached the speed drops to 1000kbps. These are fixed‑data plans rather than unlimited ones.
If a traveler needs more data, eSimfly offers higher‑cap fixed data plans such as the France Unlimited 10‑day plan, which delivers 3GB/day for 10 days, or the Bouygues Telecom 120GB plan, valid for 30 days. These options can be more cost‑effective for most users unless extremely heavy data consumption is required.
