AeroSims eSIM Data Plans for Saint Barthélemy

AeroSims does not provide a true unlimited data eSIM for Saint Barthélemy. The plans that carry the word “Unlimited” in their names actually allow 5 GB per day of high‑speed data and, after that limit, the speed drops to 512 kbps. For travelers who want a larger hard cap of high‑speed data, AeroSims offers fixed‑data plans such as the 20 GB/30 days and the 10 GB/30 days options, which provide the advertised amount of data without the speed reduction. These fixed plans can be more cost‑effective unless the user expects to consume more than the daily allowance.

AeroSims does not provide Saint Barthélemy eSIMs that include a local phone number or SMS capability; its plans for the destination are data‑only. Travelers who need voice or messaging can use VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection, but the availability of these services can vary, so it is advisable to confirm that the apps you rely on will work in Saint Barthélemy before purchasing a plan.
