TailSim does not provide a truly unlimited data eSIM for France. The plans that carry the word “Unlimited” in their name give 3 GB per day; once that daily quota is reached the speed is throttled to 1000 kbps. Therefore these plans are not unlimited in the sense of offering high‑speed data without limits.
If a traveler needs a larger, fixed data allowance, TailSim offers several fixed data plans for France. For example, a 50 GB plan valid for 30 days costs $40.99 USD, a 20 GB plan for 30 days costs $19.99 USD, and a 10 GB plan for 30 days costs $13.99 USD. These fixed data plans provide a larger total data allowance and may be more cost‑effective for most users.
