Airalo eSIM Data Plans for Saint Barthélemy

Airalo does not provide a truly unlimited data plan for Saint Barthélemy. The plans that carry the word “Unlimited” in their name actually offer a high‑speed allowance of 3GB per day, and once that daily cap is reached the speed is throttled to 1000 kbps. Therefore, while the plan remains active for the full validity period, the data volume is limited.

Instead, Airalo sells fixed‑data options. For example, the Barnet 20 GB plan is available for 15 days at $47 USD and for 30 days at $49 USD, while a 10 GB plan costs $37 USD for 7 days or $38 USD for 15 days. These fixed data plans can be more cost‑effective for users who need a larger volume of high‑speed data.

Airalo does not offer any eSIM plan for Saint Barthélemy that includes a local phone number or SMS capability. All available plans are data‑only, so travelers will need to rely on internet‑based communication. Popular VoIP services such as WhatsApp, Telegram, and iMessage can be used over the data connection for voice calls and messaging, but some destinations may block or restrict certain apps or VoIP services. Travelers should verify that the communication tools they need will work in Saint Barthélemy before purchasing an eSIM.

Airalo provides 17 single‑country data plans and 21 multi‑country plans that include Saint Barthélemy. Some of these plans offer a fixed data cap, while others cap data on a daily basis. Across all plans the price ranges from about $8 to $160, and the data allowance varies from 1 GB up to 20 GB, with validity periods spanning 3 to 365 days.
