eSIM Agora does not provide any Saint Martin eSIM plans that include a local phone number or SMS capability. The available plans are data‑only, so travelers will have no inbound or outbound voice or text services from the eSIM itself.
Users who need to make calls or send messages can rely on VoIP applications such as WhatsApp, Telegram or iMessage over the data connection. However, it is advisable to confirm that these services work freely in Saint Martin before purchasing, as some destinations may block or restrict certain apps.
