SimSmash eSIM Data Plans for Saint Martin

SimSmash does not provide a true unlimited data eSIM for Saint Martin. All plans listed for the island have a fixed data cap that must be used within a set validity period. The plans that contain the word “Unlimited” in their names, such as the Saint Martin Daily Unlimited 10GB/day for 1 Days, actually contain a 10GB high‑speed data allowance that is valid only for one day and is followed by a reduced speed after that limit is reached.

Travelers who need more data can opt for a fixed data plan, such as the 20GB for 30 days plan priced at $11.19 USD or the 10GB for 30 days plan at $5.99 USD. These fixed plans offer larger data allowances and longer validity, making them a more cost‑effective choice for most visitors.

SimSmash does not provide any eSIM in Saint Martin that includes a phone number or SMS capability. Travelers who need a local number will have to use a data‑only plan and rely on VoIP services such as WhatsApp, Telegram, or iMessage for voice and text communication. Because local access to these apps can sometimes be restricted, it is wise to check that the services you rely on are available in Saint Martin before purchasing an eSIM.

SimSmash provides a total of ten single‑country data plans for Saint Martin as well as nine multi‑country plans that include Saint Martin among their coverage. The plans cover a price range from US $0.99 up to US $58.99 and offer data caps between 1 GB and 20 GB. Most of the plans include tethering permissions, and all plans feature a fixed data allowance rather than a daily cap.
