Stellar eSim does not sell a truly unlimited high‑speed data eSIM plan for Saint Lucia. Every plan listed has a specific data cap, such as 1 GB per day in the “Unlimited”‑named bundles, 20 GB or 30 GB in the larger packages; once the allocated data is used the speed drops to 1000 kbps.
Travelers who need more data can choose a fixed‑data plan instead. For example, the Saint Lucia 50 GB 90 days plan gives 50 GB of high‑speed data during its 90‑day validity, and the 30 GB 60 days plan offers 30 GB over 60 days. Both include free Stellar VPN for the duration of the plan and provide a straightforward, cost‑effective option for those who are not extremely heavy data users.
