nextSIM does not provide a truly unlimited data eSIM for Mayotte. The plans that carry “Unlimited” in their name actually offer fixed amounts of high‑speed data—either 1 GB or 2 GB per day—and after the limit is reached the speed is throttled to 512 kbps or 2000 kbps. Because of this reduced speed, the plans are not unlimited in the sense of providing high‑speed data without limits.
If a traveler requires a larger data allowance without speed throttling, nextSIM offers fixed data plans for Mayotte, such as the 100 GB 30‑day plan priced at $181.85 USD or the 50 GB 30‑day plan at $107.24 USD. These large‑data bundles provide high‑speed internet for the full validity period and can be more cost‑effective for heavy data users.
