WonderConnect does not offer eSIM plans with a local phone number or SMS capability for travelers to Martinique. Only data‑only eSIM options are available from the provider.
Users who require voice or text services can use internet‑based messaging and calling applications such as WhatsApp, Telegram, or iMessage over the data connection, but those services might be blocked or restricted in Martinique. Travelers should check that the apps they rely on work in the destination before purchasing a plan.
