iRoamly eSIM Data Plans for Martinique

iRoamly does not provide a truly unlimited high‑speed data eSIM for Martinique. All of its plans give a fixed allowance of 500GB of high‑speed data. For example, a 1‑day plan costs $5.50 and a 30‑day plan costs $90.00; after the 500GB have been used, the speed would be throttled to a reduced level. Travelers who need more data may find a fixed‑data plan more cost‑effective than using a plan labeled “Unlimited, ” which in practice is limited to 500GB.

iRoamly does not provide a Martinique eSIM that includes a phone number or SMS capability. The plans offered to Martinique travelers are data‑only, with no inbound or outbound voice or SMS services.

Travelers can rely on VoIP applications such as WhatsApp, Telegram, and iMessage over the data connection to send messages and make calls without a local phone number.

iRoamly offers 27 single‑country plans and 104 multi‑country plans for travelers heading to Martinique. The plans include both fixed data‑cap options, which provide a set amount of data for the entire validity period, and daily‑data‑cap options that allot a specific amount of data each day. Across the catalogue, prices range from free to roughly $211, while data caps cover a spectrum from 500 MB up to 500 GB and validity ranges from 1 to 30 days.
