ZenSim does not provide a truly unlimited data eSIM for France. The plans that use the word “Unlimited” in their names give a fixed high‑speed allowance of 3 GB per day. Once the daily limit is reached, the speed is throttled, so the data is not unlimited.
Instead, ZenSim offers fixed‑data plans that may suit many travelers. For example, the France 20GB – 10 Days plan allows 20 GB of high‑speed data for ten days, and the France 10GB – 10 Days plan offers 10 GB for the same period. Choosing these fixed‑data options can be more cost‑effective unless a user requires continuous high‑speed data without any limits.
