mysim24 eSIM Data Plans for Saint Barthélemy

mySim24 does not provide any truly unlimited high‑speed eSIM plan for Saint Barthélemy.
The plans listed under the “Unlimited” or “Unlimited Plus” names give a daily data allowance (1 GB or 2 GB) at high speed, after which the connection continues at a reduced speed (512 kbps or up to 2 Mbps).

Travelers who need a larger or unrestricted data allowance can choose from mySim24’s fixed data bundles. For example, a 100 GB bundle valid for 30 days costs $60.01 USD, and a 50 GB bundle valid for 90 days costs $43.18 USD. These options provide a finite amount of high‑speed data without the day‑by‑day reset that applies to the “Unlimited” plans.

There are no mysim24 plans for Saint Barthélemy that provide a phone number or SMS capability. The provider only offers data‑only eSIM options for the destination.

Travelers who need to make calls or send messages can typically use VoIP applications, such as WhatsApp, Telegram, or iMessage, over the data connection. However, not all destinations allow unrestricted access to these services, so it is advisable to check that the apps you rely on are available in Saint Barthélemy before purchasing a plan.

mySim24 offers 32 single‑coverage plans and 39 multi‑coverage plans for Saint Barthélemy. Prices range roughly from $4 to $308, while data caps vary from 1 GB up to 100 GB. The catalog includes both fixed‑data‑cap plans—where a set amount of data is available for the plan’s validity—and daily‑data‑cap plans, in which a daily limit is applied and can reduce speed once exceeded.
