Touchdown eSIM does not offer a true unlimited data eSIM for Réunion; all listed plans have a hard data cap. The largest fixed‑data plan is “Reunion 20GB 30 Days,” which gives 20 GB usable for 30 days, and a smaller “Reunion 10GB 30 Days” plan offers 10 GB for the same period.
A special 1‑day option (“Reunion 10GB/Day - 1 Day”) provides 10 GB each day; after that allowance, data is still usable at a reduced speed of 512 kbps. Because the plan does not have an unlimited data capacity, users who expect very high data volumes will generally find that a fixed plan such as the 20 GB 30‑day offering delivers better cost efficiency.
