MobineX does not provide a true unlimited eSIM plan for Saint Lucia. The only plan that carries the label “Unlimited Standard” actually limits high‑speed data to 1 GB, after which the speed is throttled to 128 kbps. Anyone looking for more data will need to choose one of the fixed‑data options that mobineX offers for Saint Lucia, such as the 100 GB plan valid for 60 days, the 50 GB plan valid for 30 days, or the 30 GB, 20 GB, or 15 GB plans also valid for 30 days. These fixed‑data plans give a larger amount of high‑speed data without the speed reduction that accompanies the “Unlimited Standard” plan, and may be a more cost‑effective choice unless a traveler requires a truly unlimited data allowance.
