No, Lumbus does not provide an unlimited‑data eSIM for Réunion. The plans that carry the name “Réunion Unlimited” give a fixed allowance of 3GB per day for the chosen validity period; after that daily amount is used, the speed drops to 1000 kbps. For travelers who need more data without the daily limit, Lumbus offers several fixed‑data plans such as the 20GB plan for 30 days at $17.99 USD and the 10GB plan for 30 days at $8.99 USD. These plans allow higher data volumes for a set number of days and may be more cost‑effective for most users compared to a plan that throttles after a daily threshold.
