Astaroam eSIM Data Plans for Saint Barthélemy

Astaroam does not provide a genuinely unlimited data eSIM for Saint Barthélemy.
All plans that carry the word “Unlimited” actually have a fixed daily allowance of 3 GB; once that amount is used the speed drops to 1000 kbps. For travelers who need higher data volumes, Astaroam offers fixed‑data options such as a 10 GB plan that is valid for 30 days and costs $36.13 USD, and a 5 GB plan for 30 days that costs $21.42 USD. Choosing a fixed‑data plan can be more cost‑effective unless the user is an extremely heavy data consumer.

Astaroam does not provide an eSIM plan with a phone number or SMS capability for Saint Barthélemy. The eSIMs available from Astaroam for that destination are data‑only. Travelers who need to make calls or send messages can use VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection, but should verify that these services are accessible in Saint Barthélemy before purchasing a plan.

Astaroam offers six single‑country plans and five multi‑country plans for Saint Barthélemy. The plans vary in price from $3.67 to $36.13 and provide between 1 GB and 10 GB of data, with validity periods ranging from three to thirty days. Some of the plans allow tethering and reduce speed to 1000 kbps on higher‑tier options.
