AeroSims eSIM Data Plans for Saint Martin

AeroSims does not provide a truly unlimited data eSIM for Saint Martin. The plans that bear the “Unlimited” name give 5 GB of high‑speed data per day and, once that amount is consumed, the connection is throttled to 512 kbps. Beyond the daily allowance no additional high‑speed data is provided.

Instead, AeroSims offers fixed‑data plans such as 20 GB for 30 days (priced at $16.90 USD) or 10 GB for 30 days (priced at $8.90 USD). These plans supply a specified amount of high‑speed data that must be used within the validity period.

AeroSims does not provide a Saint Martin eSIM that includes a phone number or SMS capability. Travelers looking for voice and text services will need to rely on internet‑based VoIP applications such as WhatsApp, Telegram, or iMessage, which can normally be used over the data connection. Because some destinations may block or restrict certain apps, it is advisable to verify that the VoIP services you plan to use are accessible in Saint Martin before buying an eSIM.

AeroSims lists 11 single‑country data plans for Saint Martin and 6 multi‑country plans that include the island among other destinations. The plans vary in price from about $3.90 to $87.86, and data caps range from 3 GB up to 20 GB, with validity periods between one and thirty days. Some offers have a fixed data amount for the entire validity period, whereas others impose a daily data cap, limiting the amount that can be used each day.
