Lumbus eSIM Data Plans for Saint Martin

Lumbus does not provide a true unlimited data eSIM for Saint Martin. All of its plans that list “Unlimited” in the name actually offer a fixed high‑speed allowance of 3 GB per day for the validity period, after which the speed would be reduced.

If you require more data without a daily limit, Lumbus offers several fixed‑data options. For example, a 20 GB plan is available for 30 days at $18.99 USD, while a 10 GB plan can be purchased for $8.99 USD and a 5 GB plan for $5.99 USD, all of which are valid for 30 days. These high‑data‑allowance plans give travelers a cost‑effective alternative to the daily‑cap “Unlimited” plans when a larger total data volume is needed.

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.
