ZenSim does not provide a truly unlimited high‑speed data eSIM for Mayotte. The plans that carry “Unlimited” in their name actually contain a daily data cap of 3 GB and do not offer unrestricted data. After the cap is reached, users experience a reduced speed, though the exact throttled rate is not specified.
Travelers looking for broader data coverage can consider ZenSim’s fixed‑data plans. For example, a 20 GB plan is available for 10 days or 30 days, and a 10 GB plan is offered for the same validity periods. These options provide larger high‑speed data allowances while keeping costs predictable, which may be more economical for travelers who use a moderate or high amount of data.
