Saily does not provide a truly unlimited high‑speed data eSIM for France. The plans that carry the name “UNLIMITED” in the Saily catalogue actually offer a fixed amount of high‑speed data—5 GB per day for the France UNLIMITED series or 30 GB for the Global UNLIMITED 30‑day plan—and a reduced speed of 1024 kbps once that daily or total limit is reached. Therefore, they are not unlimited in the sense of offering data without any cap.
For travelers seeking a fixed quantity of high‑speed data, Saily offers several paid plans that specify an exact data allowance. For instance, the France 20GB 30‑day plan costs $31.99 USD and gives 20 GB of high‑speed data for 30 days, while the France 10GB 30‑day plan offers 10 GB for the same period at $19.99 USD. These fixed‑data options provide a clear cost‑to‑usage relationship and may be more cost effective for users who do not need a large amount of data or who plan to use a consistent amount.
