MobiMatter does not provide an unlimited‑data eSIM for Réunion. The catalog lists only fixed data plans with caps of 10 GB, 20 GB or 50 GB and corresponding validity periods of 15, 30, 180 or 365 days. Travelers who need a large data allowance can choose one of the fixed plans, such as the 50 GB 180‑day Best World package or the 20 GB yearly Global Special, which may be more cost‑effective unless an extremely heavy data user requires continuous data usage.
