Kolet does not provide any eSIM plan for Martinique that includes a phone number or SMS capability. Travelers who purchase a Kolet eSIM for Martinique will receive only a data‑only connection, so traditional voice calls and text messages cannot be sent or received.
However, the data connection can be used with VoIP applications such as WhatsApp, Telegram, and iMessage to make calls and send messages. Because some destinations may block or restrict certain apps or VoIP services, it is advisable to confirm that the preferred communication apps are accessible in Martinique before making a purchase.
