SimBalkan eSIM Data Plans for Saint Martin

SimBalkan does not provide a plan that offers truly unlimited high‑speed data in Saint Martin. The plans that carry the “Unlimited” name actually allow only 1 GB of 5G data per day, after which the speed is throttled to a reduced level.

Travelers looking for more data can choose one of SimBalkan’s fixed data plans. For example, a 5 GB plan is available for 30 days at $4.54 USD, and a 10 GB plan is priced at $6.86 USD for the same period. There is also a 20 GB option for 30 days that costs $12.68 USD. These fixed bundles give a larger data allowance and can be more cost‑effective for most visitors.

SimBalkan does not offer an eSIM plan with a phone number or SMS capability for Saint Martin. The provider only sells data‑only eSIMs for that destination.

Travelers can still use VoIP services such as WhatsApp, Telegram, or iMessage over the data connection, but accessibility of these apps may vary. It is advisable to verify that the messaging or calling applications you rely on are available in Saint Martin before making a purchase.
