Silvy eSIM Data Plans for Saint Martin

Silvy does not provide an unlimited data eSIM plan for Saint Martin. All current Silvy plans for the island have a fixed data cap.

If unlimited usage is not required, Silvy offers several high‑capacity options. For example, the Saint Martin 20GB for 30 days plan costs $87.90 USD and allows tethering on 5G networks, while a smaller 10GB for 30 days plan is available for $54.90 USD. Selecting a fixed‑data plan can be more economical for most travelers, unless the need for data usage is very high.

Silvy does not provide a Saint Martin eSIM that includes a phone number or SMS capability. The plans that Silvy offers for Saint Martin are strictly data‑only; travelers who want voice or text services can use internet‑based apps such as WhatsApp, Telegram, or iMessage, though some destinations may restrict access to these services, so it is advisable to confirm that the apps you need will work in Saint Martin before purchasing.

There are five single‑country data plans available from Silvy for Saint Martin, and none of them are multi‑country packages. The plans are sold at prices ranging from about $8.50 to $87.90, each providing between 1 GB and 20 GB of data that can be used over a validity window of 7 to 30 days. The offerings are all fixed‑data plans; each plan delivers a set data amount rather than a daily cap. Tethering is allowed on some of the plans, giving travelers the option to share the connection with other devices.
