SimSmash eSIM Data Plans for Saint Barthélemy

SimSmash does not provide a true unlimited‑data eSIM for Saint Barthélemy. The plans that carry the word “Unlimited” in their names actually include a fixed amount of high‑speed data—ranging from 1 GB to 10 GB per day—and once that amount is used the speed is reduced, not the data cap. Travelers who need a larger data allowance can choose from the fixed data plans available, for example the 20 GB for 30 days option or the 10 GB for 30 days plan, which allow a set volume of high‑speed data to be used over a month before the balance rolls over.

SimSmash does not provide a Saint Barthélemy eSIM that includes a phone number or SMS capability. The only plans available from SimSmash for Saint Barthélemy 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 is not guaranteed and should be confirmed before purchasing.

SimSmash offers ten single‑country plans and nine multi‑country plans for Saint Barthélemy. The plans vary in price from about $1.19 to $58.99 and in data cap from 1 GB up to 20 GB.
