iRoamly does not provide a true unlimited data eSIM plan for Réunion. All of its listed plans for the island have a hard data cap of 500GB, even though their names include the word “Unlimited.” Once the 500GB allowance is used, the speed is throttled to 384kbps as stated in the features.
Instead, iRoamly offers fixed data plans of 500GB that can be purchased for 1 to 30 days, with prices ranging from $23.00 USD for a single day to $633.50 USD for thirty days. These plans give access to 5G coverage across Réunion and the fourteen other countries in the Africa‑17 Countries bundle, and they support tethering. Choosing a fixed data plan can be more cost‑effective unless a traveler needs data beyond the 500GB limit.
