Lumbus does not provide a true unlimited high‑speed data eSIM for France. The plans labeled “France Unlimited” and “Europe 33 Unlimited” give 3 GB of high‑speed data per day for 3, 7, 14 or 30 days; after the daily allowance the speed drops to 1 Mbps rather than remaining unlimited.
If you need more data, Lumbus offers fixed‑data plans such as the France 50 GB plan valid for 30 days ($33.99 USD) or for 180 days ($43.99 USD). These options provide a larger fixed allowance and, because they are not capped by daily limits, can be a cost‑effective choice for travelers who expect to use a substantial amount of data.
