eSIMCard eSIM Data Plans for Saint Martin

eSIMCard does not provide a truly unlimited high‑speed data eSIM for Saint Martin. All plans labeled “Unlimited” in the directory have a maximum data allowance—either 1 GB per day or 2 GB per day—and after that quota is reached the speed is throttled to 500kbps or 2000kbps.

If an unlimited plan is not required, eSIMCard offers fixed data options that may better suit heavy usage. For example, the 20 GB eSIM Data For 30 days in Saint Martin costs USD 64.22 and provides unthrottled access, while the 100 GB Global unthrottled plan runs for 180 days at USD 430.64 and covers Saint Martin in addition to 149 other countries. These plans give a larger data allowance without the speed reductions that appear after the “unlimited” daily caps.

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.
