Billion Connect does not provide a Mayotte eSIM that includes a phone number or SMS capability. Travelers can only purchase data‑only plans from this provider for the destination.
Without a local phone number or SMS support, users can still communicate through internet‑based services such as WhatsApp, Telegram, or iMessage while connected to the eSIM data network. Because some destinations can block or restrict certain VoIP applications, it is advisable for travelers to confirm that the messaging or calling apps they rely on remain accessible in Mayotte before purchasing a plan.
