MobiMatter does not offer an eSIM for Mayotte that includes a phone number or SMS capability. The provider sells only data‑only plans for this destination. If callers and text messages are required, travellers can use internet‑based services such as WhatsApp, Telegram, or iMessage. Because access to some VoIP applications can be restricted in certain regions, it is advisable to verify that the apps you rely on are available in Mayotte before purchasing.
