RoameSIM eSIM Data Plans for Saint Martin

RoameSIM does not currently offer any truly unlimited data eSIM plans for Saint Martin. Although the plans that carry the “Unlimited” label provide 3 GB of high‑speed data each day, the speed is reduced to 1000 kbps after that limit is reached. For travelers who need a larger contiguous data allowance, RoameSIM provides fixed‑data plans such as a 20 GB plan valid for 30 days or a 60 GB plan valid for 125 days, both of which include tethering and use 5G networks.

RoameSIM does not provide an eSIM for Saint Martin that includes a local phone number or SMS capability. The available plans are data‑only, so users will need to rely on internet‑based services such as WhatsApp, Telegram, or iMessage to make calls and send messages.

RoameSIM offers 9 single‑country plans that include Saint Martin and 19 multi‑country plans that cover the island. The available plans range in price from roughly $2.40 to $208.60 and in data capacity from 200 MB up to 60 GB. Some of the plans provide a fixed data amount, while others feature a daily data cap that allows the user to download a set amount each day. The variety of validity periods, from 3 to 365 days, gives travelers flexibility depending on how long they stay.
