Skyalo does not provide an unlimited data eSIM for Mayotte. The available options are fixed‑data plans that have a set data allowance and validity period. For example, Skyalo offers a 20 GB plan that is valid for 30 days and a 10 GB plan for the same duration.
Because each plan has a hard data cap, a fixed‑data plan can be more cost effective unless the traveler is an extremely heavy data consumer who would prefer a pay‑as‑you‑go balance that can be topped up at any time.
