nextSIM does not provide a truly unlimited data eSIM for Saint Lucia. The plans that include “Unlimited” in their name actually offer a fixed amount of high‑speed data (1 GB or 2 GB per day) and throttle the speed to 512 kbps or 2000 kbps once the cap is reached, which means the data is not without limits.
If a traveller needs more data, nextSIM offers fixed‑data plans such as a 20 GB plan valid for 30 days, a 50 GB plan valid for 30 days, and other higher‑volume options like 30 GB or 40 GB for 30 days. These fixed‑cap plans can be more cost‑effective for users who consume a large amount of data during their stay.
