SeferESIM does not offer an unlimited data eSIM for Saint Barthélemy. The provider’s plans in the dataset provide fixed data allowances that must be used within a specified validity period. For example, the Saint Barthelemy 20GB 30Days plan gives 20GB of data for 30 days at $18.64 USD, and the Global139 20GB 90Days plan offers the same 20GB for 90 days at $179.36 USD. There is also a 10GB per day plan that supplies 10GB for a single day and another 10GB for 30 days plan.
These fixed data plans can be more cost‑effective unless a traveler is an extremely heavy data consumer. They allow travelers to budget for a known amount of data within a clear time window, whereas no unlimited option is available for Saint Barthélemy through SeferESIM.
