SimSmash eSIM Data Plans for Saint Barthélemy

SimSmash does not offer a truly unlimited data eSIM for Saint Barthélemy. Plans that carry “Unlimited” in their name, such as the Saint Barthelemy Daily Unlimited 1GB/day, 2GB/day, 3GB/day, 5GB/day, and 10GB/day for 1 day, each provide a fixed amount of high‑speed data and would throttle speed after the limit is reached. For travelers who need more data, SimSmash has fixed‑data options such as the 20GB for 30 days plan priced at $10.99 USD and the 10GB for 30 days plan priced at $5.79 USD. Choosing a fixed‑data plan can be more cost effective unless you are an extremely heavy data user.
