Simsima eSIM Data Plans for Saint Barthélemy

Simsima does not provide a truly unlimited data eSIM for Saint Barthélemy. All of the plans listed contain a hard data cap: the two plans with “Unlimited” in the name give 3 GB per day and throttle speed to 1000 kbps after that daily limit, while the other options provide fixed amounts such as 20 GB for 30 days or 10 GB for 30 days. Travelers who want a set amount of high‑speed data can choose from these fixed‑data plans, which offer a larger data allowance than the 3 GB/day so‑called unlimited plans and are often more cost‑effective unless very heavy usage is anticipated.

Simsima does not provide eSIM plans that include a phone number or SMS for Saint Barthélemy. Their offerings for this destination are strictly data‑only. Travelers who need voice or messaging can use VoIP services such as WhatsApp, Telegram, or iMessage over the data connection, but availability of those apps can vary, so it is advisable to confirm that the apps you rely on are accessible in Saint Barthélemy before purchasing a plan.

Simsima offers one single‑country plan for Saint Barthélemy. No multi‑country plans that include this island are listed in the database. The available plans span a price range of roughly $5.63 to $90.55 and a data capacity between 1 GB and 20 GB, with validity periods from 5 to 365 days. The single‑country option is a fixed data cap plan, meaning the data allowance is a set amount that does not reset daily.
