eSIMCard’s “Unlimited” plans for Madagascar do not provide a true unlimited data allowance. Each of those plans caps high‑speed data at 1 GB (or 2 GB for the Plus variants) per day, after which the connection is throttled to a reduced speed of 500 kbps or 2000 kbps. Therefore, an unlimited high‑speed data eSIM is not offered by eSIMCard for Madagascar.
If a user needs a larger, non‑throttled data allowance, eSIMCard sells fixed data plans. For example, the 100 GB 180‑day plan (unthrottled) and the 50 GB 90‑day plan give substantial high‑speed data without a daily cap, though the prices differ. Choosing a fixed data plan can be more cost‑effective for travelers who require significant data use.
