Yes. ESIM.DOG offers several unlimited plans for Réunion that are valid for a set number of days, ranging from 1 day to 30 days. Prices for these plans vary accordingly, with the 1‑day option starting at $1.39 USD and the 30‑day option at $14.06 USD. The data allowance is listed as Unlimited for each plan, but speeds may be throttled with a maximum speed of 1000 kbps; after heavy usage speeds can be reduced under a fair usage policy.
If a user is unsure how far the speed reduction might apply or is concerned about potential throttling, they should contact ESIM.DOG directly for confirmation of their Fair Usage Policy and typical data availability at normal speed.
