CloudOn eSIM eSIM Data Plans for Saint Martin

There are no true unlimited data eSIM plans for Saint Martin offered by CloudOn eSIM. The plans that carry “Unlimited” in their names actually provide a fixed amount of high‑speed data—3 GB per day on French‑part Saint Martin plans or 2 GB per day on the global variants—and after that limit is reached the connection speed drops to 1 Mbps.

For travelers needing a larger amount of data without a hard cap, CloudOn eSIM offers fixed data plans such as the Saint Martin (French Part) 20 GB for 30 days plan and a 5 GB plan valid for 30 days. These fixed plans can be more cost‑effective for most users, especially those who do not foresee using unlimited data.

CloudOn eSIM does not provide a Saint Martin eSIM that includes a phone number or SMS capability. The provider only offers a data‑only plan for Saint Martin, so travelers cannot place or receive standard voice calls or send SMS messages directly through the eSIM network.

Travelers who need voice or messaging can use VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection, but they should confirm that these services are accessible in Saint Martin before purchasing, as some destinations may block or restrict certain apps or services.

CloudOn eSIM currently provides 10 single‑country plans that cover Saint Martin, and 6 multi‑country plans that include the island as part of a broader regional bundle. Available plans range in price from $5.99 to $131.49 and offer data caps between 1 GB and 20 GB. Customers can choose between fixed‑data plans, which provide a set amount of data for the plan’s validity period, or daily‑data‑cap plans that reset the data allowance each day.
