Lumbus eSIM Data Plans for Saint Martin

Lumbus does not provide a truly unlimited data eSIM for Saint Martin. All plans named “St. Martin Unlimited” give 3 GB per day and drop to a reduced speed of 1000 kbps once the daily allowance is used, which is not the same as an unlimited high‑speed plan. Travelers who need more data can choose from Lumbus’s fixed data plans, such as the 20 GB 30 day bundle or the 10 GB 30 day bundle, which offer larger high‑speed allowances for a set validity period.

Lumbus does not provide a Saint Martin eSIM plan that includes a phone number or SMS capability. Travelers who purchase an eSIM from Lumbus for Saint Martin will receive only a data‑only plan.

Those users can still communicate via data‑based applications such as WhatsApp, Telegram, or iMessage, but they should check in advance that these services are accessible in the destination, as some mobile networks may block or limit certain VoIP applications.

Lumbus lists nine single‑country data plans for Saint Martin and does not offer any multi‑country options. The available plans cover prices from roughly $3.99 to $62.99, with data caps ranging between 3 GB and 20 GB and validity periods from 3 to 30 days. Among the nine plans, four feature a daily data cap while five have a fixed data allowance, and some plans allow tethering.
