eSIMCard eSIM Data Plans for Saint Martin

eSIMCard does not provide a truly unlimited data eSIM for Saint Martin. All plans that use the word “Unlimited” in their name are in fact capped at 1 GB or 2 GB per day, and once that amount is reached the connection is throttled to 500 kbps or 2000 kbps.

Instead, eSIMCard offers fixed‑data options that give larger, unthrottled allowances. For example a 20 GB plan valid for 30 days costs $64.22, and a 100 GB global plan for 180 days is priced at $430.64. These fixed plans may be more economical for travelers who expect to use more data than the capped “Unlimited” options allow.

eSIMCard does not provide a phone number or SMS capability for its Saint Martin eSIM. The provider offers only data‑only plans in this destination, so you will not receive inbound or outbound voice and SMS services. You can use popular VoIP applications such as WhatsApp, Telegram and iMessage to make calls and send messages over the data connection.

eSIMCard offers a range of data plans that cover Saint Martin, including 20 single‑country plans and 14 multi‑country plans. The catalog includes both fixed‑data plans—where a set amount of data is allocated for the entire validity period—and daily‑data‑cap plans that reset each day, providing flexibility for short stays. Prices for Saint Martin plans vary from about $5.06 to $430.64, while data caps range from 1 GB up to 100 GB and validity can span 1 to 365 days. Many plans allow tethering, and some include reduced speed options of 500 Mbps or 2000 Mbps for periods when network traffic is high.
