eSimfly eSIM Data Plans for Martinique

eSimfly does not provide a truly unlimited high‑speed data eSIM for Martinique. The plans that carry “Unlimited” in their names, such as Martinique Unlimited 3 days and Martinique Unlimited 30 days, actually allow 3 GB per day. After the daily limit is reached, the speed is throttled, so the data is not unlimited.

Instead, eSimfly offers fixed data plans that can be more cost‑effective for typical travelers. For example, a 20 GB plan valid for 30 days costs about $26.35 USD, and a 10 GB plan for 30 days costs around $16.66 USD. These plans provide a large amount of high‑speed data without the daily cap, making them a practical alternative for users who do not need an unlimited supply.

eSimfly does not provide a Martinique eSIM that includes a local phone number or SMS capabilities. The only eSIMs available from eSimfly for Martinique are data‑only plans, so travelers can use services such as WhatsApp, Telegram, or iMessage over the data connection for calls and messaging.

Martinique is covered by 12 single‑country data plans and 11 multi‑country data plans from eSimfly. The plans span a price range of roughly $3.57 to $103.02 and data caps from 1 GB up to 20 GB. Some plans offer a fixed data amount, while others use a daily data cap to determine the usable data during the validity period. Certain plans also allow tethering, which can be helpful for travelers who need to share the connection with multiple devices.
