Yesim eSIM Data Plans for Saint Martin

Yesim offers unlimited data eSIM plans for Saint Martin. Two unlimited options are available: a 1 days plan priced at $20.69 USD covering Saint Martin plus 14 neighbouring countries, and a 1 days plan priced at $50.58 USD covering only Saint Martin.

Both plans allow tethering, but the data may be throttled after heavy usage according to Yesim’s fair‑usage policy. If a user is concerned about potential speed restrictions, they should contact Yesim directly to confirm the policy limits and the amount of data that remains at normal speed.

Yesim does not provide a telephony plan that includes a phone number or SMS capability for travelers visiting Saint Martin. Only data‑only eSIMs are sold by Yesim for this destination.

To communicate while abroad, users can rely on internet‑based messaging and calling apps such as WhatsApp, Telegram, or iMessage, which operate over the data connection and do not require a local phone number or SMS functionality.

Yesim provides four single‑country plans and four multi‑country plans for Saint Martin. Prices range between $20.69 and $75.88, while data caps vary from 1 GB to unlimited, with validity periods from one to thirty days. In some offerings a fixed data amount is allocated for the entire validity, whereas others permit an unlimited data allowance that may be subject to throttling after usage thresholds are met.
