eSimfly eSIM Data Plans for Saint Martin

eSimfly does not provide a truly unlimited data eSIM for Saint Martin. The plans that carry the word “Unlimited” in their name actually have a fixed data allowance: 3 GB per day for the French part of Saint Martin or 35 GB for the international version, and after the limit is reached the speed is throttled to 1000 kbps. Therefore these plans are not unlimited in the sense of offering high‑speed data without limits.

Travelers who need a large amount of data can choose from eSimfly’s fixed data plans. For example, a 5 GB plan valid for 30 days or a 10 GB plan valid for 30 days provide substantial data, and the 35 GB international plan valid for 30 days offers an even larger allowance. These fixed data plans can be more cost‑effective for users who consume a lot of data.

eSimfly offers a Saint Martin eSIM that includes a full telephony package. The plans available provide 35 GB of data for 30 days, with prices ranging from $29.90 USD to $35.88 USD. Each plan assigns a phone number with the dialing code +44, enabling inbound and outbound calls and inbound and outbound SMS. Travelers who need a phone number and SMS capability in Saint Martin can purchase one of these eSIM plans, though it is worthwhile to confirm specific details with eSimfly before ordering.

eSimfly offers nine single‑country plans and nine multi‑country plans that are valid for Saint Martin. The plans span a price range of about $3.65 to $67.27 and offer data caps from 1 GB up to 35 GB, with validity periods between 3 and 30 days. Some plans provide a fixed data amount for the entire validity, while others impose a daily data cap. Both types are available for customers travelling to or within Saint Martin.
