AirPlans eSIM Data Plans for Saint Barthélemy

AirPlans does not provide a true unlimited‑data eSIM for Saint Barthélemy. The plans that carry the word “Unlimited” in their name give a fixed amount of high‑speed data—1 GB per day for the 1‑day and a 3 GB/day allowance for longer durations—and after that data a reduced speed is applied (512 kbps or 1 Mbps).

If you need more data, you can choose one of AirPlans’ fixed data plans. For example, the 20 GB 30‑day plan costs $17.14 USD, and the 50 GB 30‑day plan is $219.91 USD. These plans offer a larger high‑speed data allowance without the speed reduction that applies to the “Unlimited” options.

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.
