MobileSIM eSIM Data Plans for Saint Martin

MobileSIM does not provide a truly unlimited high‑speed data eSIM for Saint Martin. All plans that carry the “Unlimited” name impose a 3 GB per day cap; after this threshold the speed drops to 1000 kbps.
For travelers who need more data without a daily limit, MobileSIM offers fixed‑data plans such as 60 GB for 125 days, 20 GB for 30 days, 10 GB for 30 days, or 5 GB for 30 days. These plans provide a larger total data allowance and avoid the daily speed restriction, making them a more cost‑effective option for heavy data users.

MobileSIM does not provide an eSIM for Saint Martin that includes a local phone number or SMS capability. The provider offers only data‑only plans for travelers who wish to connect to the internet in Saint Martin. You can still use VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection, although some destinations may block or restrict certain apps, so it is wise to confirm that the messaging or calling services you rely on are accessible in Saint Martin before purchasing.
