Saily eSIM Data Plans for Saint Martin

Saily does not provide a truly unlimited data eSIM for Saint Martin. All of Saily’s plans for the island have a fixed data allowance, the largest of which is 30 GB per validity period.

The agency does offer sizable fixed‑data plans as alternatives. For example, a 30 GB plan that lasts 90 days is available for US $119.99, and a 20 GB plan that lasts 365 days costs US $66.99. If a plan carries the label “UNLIMITED” in its name, it still includes a 30 GB cap; after the allowance is used, the speed drops to 1024 kbps or 1 kbps, depending on the product. Choosing a fixed‑data option may be more cost‑effective unless a traveler expects to consume well over 30 GB of high‑speed data.

Saily does not provide a Saint Martin eSIM with a local phone number or SMS capability. Only data‑only eSIM plans are available for Saint Martin from this provider. Travelers who need messaging or voice functionality can use WhatsApp, Telegram, iMessage, or other VoIP services over the data connection.

Saily provides 4 single‑country plans and 15 multi‑country plans for Saint Martin. The available options range in price from $8.49 to $159.99 and in data capacity from 1 GB to 30 GB.
