AirPlans eSIM Data Plans for Saint Barthélemy

AirPlans does not provide a truly unlimited data eSIM for Saint Barthélemy. The plans that carry the word “Unlimited” in their names actually have a hard data cap—either 1 GB per day or 3 GB per day—and after that limit the speed is reduced to 512 kbps or 1000 kbps. Therefore, these plans are not unlimited in the sense of offering high‑speed data without limits.

If you need a larger data allowance, AirPlans offers fixed data plans such as 50 GB for 30 days, 20 GB for 30 days, 18 GB for 30 days, or a 10 GB plan for 1 day. These plans provide a set amount of high‑speed data that must be used within the specified validity period. Choosing a fixed data plan can be more cost‑effective unless you are an extremely heavy data consumer.

AirPlans does not provide an eSIM for Saint Barthélemy that includes a phone number or SMS capability. Only data‑only eSIMs are available for this destination. Travelers who need voice or messaging can use VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection, but they should confirm that those services are accessible in Saint Barthélemy before purchasing, as some destinations may restrict or block certain apps or VoIP services.

AirPlans offers two data plans for Saint Barthélemy, one single‑country plan and one multi‑country plan that includes the island in a regional bundle. The single‑country option delivers a fixed data amount—typically 2 GB to 5 GB—for a period of up to 30 days and costs between roughly $15 and $45. The multi‑country package, which covers various Caribbean destinations, provides a larger data allowance ranging from 10 GB to 30 GB for the same validity window and is priced between about $80 and $150. Both plans feature tethering where allowed and offer optional reduced speeds if required.
