eSimfly does not provide a true unlimited data eSIM for Saint Barthélemy.
The plans that carry the word “Unlimited” in their names offer a fixed daily allowance of 3 GB, after which the data speed falls to 1000 kbps. Alternative fixed‑data options are also available, such as a 10 GB plan valid for 30 days, which does not include a reduced speed after the limit is reached. Choosing a fixed‑data plan can be more cost‑effective unless a traveler needs continuous high‑speed data without any cap.

Travelers who need voice or messaging services can use VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection. However, some destinations may block or restrict access to certain apps or VoIP services, so it is advisable to verify that the services you rely on are accessible in Saint Barthélemy before purchasing a plan.
