Simsima does not offer a truly unlimited data eSIM for Madagascar. The plan called “Unlimited - 10 days” is actually limited to 3 GB per day; after that a reduced speed of 1000 kbps applies. All other Madagascar‑only plans have a fixed data cap—20 GB for 30 days or 365 days, and a 10 GB for 30 days option. These are fixed‑data plans, meaning the data is consumed within the specified validity period and no further usage is possible once the cap is reached. For users needing more data, the largest available options are the 20 GB plans, which provide ample data for most travel needs while keeping costs predictable.
