Roamify offers unlimited data eSIM plans that cover Madagascar. The unlimited options are available for validity periods ranging from 1 day to 30 days, with prices from $15.00 for a 1‑day plan up to $266.00 for a 30‑day plan. The plans include tethering, but the listed speed may be throttled after heavy use; Roamify applies a fair‑usage policy that can reduce speeds after extensive traffic. If you are concerned about potential speed restrictions, you can contact Roamify to confirm the typical amount of data that remains at normal speed for each validity period.
