MicroEsim eSIM Data Plans for Saint Barthélemy

MicroEsim does not offer a true unlimited‑data eSIM for Saint Barthélemy. The products listed as “Unlimited” actually provide a 1GB/day high‑speed allowance; after the daily limit is reached the speed drops to 5000kbps.

Instead, MicroEsim sells fixed‑data plans for Saint Barthélemy, such as a 30GB package valid for 30 days (price $27.30 USD) or a 60GB package valid for 60 days (price $87.13 USD). When the allocated data is exhausted, the network throttles the speed to 128kbps. These fixed plans may be more cost‑effective for travelers who need a large amount of data but are not extremely heavy users.

MicroEsim does not provide an eSIM with a phone number or SMS capability for travelers visiting Saint Barthélemy. The provider offers only data‑only eSIMs in this destination. Travelers who need messaging or calling can use VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection, which do not require a local phone number or SMS service.

MicroEsim offers 115 multi‑country data plans for Saint Barthélemy; no single‑country plans are available. The plans span a price range from $0.99 to $88.78 and data caps between 500 MB and 60 GB. They come in two formats: daily data cap plans, where a fixed amount of data is available each day, and fixed data cap plans, where a set amount of data is usable for the entire validity period.
