Yesim eSIM Data Plans for Martinique

Yesim offers an unlimited data eSIM plan for Martinique. The plan, named Caribbean, is valid for 1 day, costs $21.10 USD, and is delivered over a 5G network. It includes tethering and is subject to a Fair Usage Policy, meaning speed may be throttled after heavy usage. Coverage spans Martinique and 14 additional Caribbean countries. Travelers who need to confirm how much data can be used at normal speed before throttling should contact Yesim directly for details about the Fair Usage Policy.

Yesim does not offer a Martinique eSIM plan that includes a local phone number or SMS capability. All plans sold by Yesim for Martinique are data‑only. Travelers can still use VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection for voice and messaging.

Yesim provides three single‑country data plans and four multi‑country plans that include Martinique, for a total of seven options. Prices run from roughly $20.76 to $76.13, while data caps range from 3 GB up to unlimited, with validity periods of 1 to 30 days. Some plans allow tethering, although speed may be throttled once the data cap is reached.
