Ubigi eSIM Data Plans for Saint Martin

Ubigi does not provide an unlimited data eSIM plan for Saint Martin. Instead the provider offers fixed‑data plans that range from 20GB for 7 days to 60GB for 30 days. For example, the BEST CARIBBEAN plan delivers 60GB of data for 30 days at $69.00 USD, and a smaller 50GB plan is available for 30 days at $188.00 USD. These high‑data‑allowance options can be more cost‑effective for most travelers unless they need continual, unlimited connectivity.

Ubigi does not offer an eSIM plan that includes a local phone number or SMS capability for Saint Martin. The only Ubigi offerings in that territory are data‑only eSIMs. Travelers can still use messaging and voice services over the data connection, such as WhatsApp, Telegram, and iMessage, which work without a dedicated phone number or SMS support.

Ubigi offers a total of 19 distinct data plans in Saint Martin, from short‑term local options to broader regional packages. There are two single‑country plans that provide coverage solely on the island, while a further seventeen plans allow usage across multiple countries in the Caribbean. The available plans span a price range of approximately $4 to $240, and data caps vary between 500 MB and 60 GB. Some of the plans are based on a fixed amount of data for the validity period, whereas others include a daily data cap that is calculated on a per‑day basis throughout the validity window. This range of options gives travelers the flexibility to choose a package that matches both their budget and data needs.
