mobineX does not provide a truly unlimited data eSIM for Saint Lucia. The plan that bears the “Unlimited” name, Unlimited Standard, actually offers 1 GB of high‑speed data, after which the speed is reduced to 128kbps. Because the data cap is 1 GB, the plan is not truly unlimited in the sense of providing unlimited high‑speed data.
Instead, mobineX offers fixed high‑data plans that can serve travelers’ needs. For example, a 100 GB plan valid for 60 days costs $652.50 USD, and a 50 GB plan valid for 30 days costs $340.50 USD. Other options include a 30 GB plan for 30 days and a 20 GB plan for 365 days. These fixed‑data plans are often more cost effective unless a traveler requires extremely heavy data usage.
