Yesim eSIM Data Plans for Martinique

Yesim offers unlimited data eSIM plans for Martinique under its Caribbean package. Customers can purchase a 1‑day unlimited plan for $20.51 USD or a 7‑day unlimited plan for $143.57 USD, both of which include tethering. The plans operate on 5G networks.

These unlimited plans come with a Fair Usage Policy: while data is unlimited, speed may be reduced after heavy use. Travelers who are concerned about potential throttling can contact Yesim directly to confirm whether the FUP applies and how much data remains available at normal speed.

Yesim does not offer any Martinique eSIM plans that include a phone number or SMS capability. Only data‑only eSIMs are available, so travelers cannot receive inbound or outbound voice calls or standard SMS through the eSIM. Users can still communicate using internet‑based services such as WhatsApp, Telegram, or iMessage over the data connection, but availability of these apps can be restricted in some destinations, so it is advisable to confirm beforehand that the necessary VoIP services work in Martinique.

Yesim offers a total of 9 data plans in Martinique, comprising 4 single‑country plans that cover only Martinique and 5 multi‑country plans that include Martinique along with other destinations. The plans range in price from $11.39 to $75.15 USD and in data cap from 1 GB up to unlimited. Some plans provide a fixed data allowance while others allow a daily data cap, giving travelers flexibility depending on their usage needs.
