Voyasim does not provide a Mayotte eSIM that includes a phone number or SMS capability. Travelers can only purchase data‑only plans from this provider. However, they can still use VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection for voice and messaging, though some destinations may restrict access to these services, so it is advisable to confirm that the apps you rely on work in Mayotte before buying a plan.
