eSIMCard does not provide a truly unlimited‑data eSIM for Réunion. All of its Réunion‑specific plans are capped at either 1 GB (or 2 GB) per day, or a single high‑speed data purchase such as 35 GB for 30 days or 50 GB for 60 days. Plans that carry “Unlimited” in the name have a hard data limit; once that limit is reached the connection is throttled to a reduced speed (512 kbps for the 1 GB plans or 2000 kbps for the 2 GB plans).
If an unlimited‑tethering experience is required, a fixed data plan may be more cost‑effective. For example, the 50 GB Data For 60 days plan offers uninterrupted high‑speed data without throttling, and the 35 GB Data & Unlimited Minutes plan gives a sizeable data allowance for 30 days. These plans illustrate the available alternatives while clarifying that no plan delivers unlimited high‑speed data.
