iRoamly eSIM Data Plans for Saint Barthélemy

iRoamly does not offer truly unlimited data eSIM plans for Saint Barthélemy. All of its listed plans for the island have a fixed data cap of 500GB, even though the plans are titled “Unlimited.” Once the 500GB threshold is reached, the network speed is reduced, but the specific throttled speed is not disclosed in the available information.

For travelers who need large amounts of data, iRoamly provides fixed‑data alternatives. A 500GB plan valid for 7 days costs $21.00 USD, and a 500GB plan valid for 30 days costs $88.00 USD. These fixed‑data options can be more cost‑effective for heavy data users compared to short‑term plans, as they avoid the speed reduction that would occur if the data cap were exceeded.

iRoamly does not offer eSIM plans for Saint Barthélemy that include a phone number or SMS capability. Travelers who need a phone number or the ability to send SMS will have to use a data‑only plan and can rely on VoIP applications such as WhatsApp, Telegram or iMessage to make calls and send messages over the data connection.
