aloSIM does not offer an eSIM for Mayotte that includes a phone number or SMS capability. Travelers can only purchase a data-only plan, which provides high‑speed internet via 4G or 5G but no traditional voice or text services.
Over the data connection, VoIP applications such as WhatsApp, Telegram and iMessage can generally be used for calls and messaging, allowing travelers to communicate without a local number. However, the availability of these services can vary; some destinations may block or restrict access to specific apps or VoIP platforms, so it is advisable to confirm that the apps you rely on work in Mayotte before purchasing.
