Skyalo does not provide an eSIM for Martinique that includes a phone number or SMS capability. The available plans are data‑only.
Travelers can use the data portion of a Skyalo eSIM to run VoIP applications such as WhatsApp, Telegram or iMessage for voice and messaging. However, some destinations may block or restrict access to these services, so it is advisable to confirm that the apps you rely on are reachable in Martinique before buying a plan.
