Supera link does not provide an unlimited data eSIM for South Korea. Travelers who need a broader data allowance can choose from fixed‑cap plans. For example, a 20 GB plan is available for 30 days at $13.49 USD and a 15 GB plan for 30 days at $11.07 USD, both offering 3G/4G/5G coverage within South Korea. If a smaller, more budget‑friendly option is preferred, a 5 GB plan for 30 days is offered at $5.35 USD, or a 5 GB/1‑day plan at $3.64 USD. Selecting a fixed data package can be more cost‑effective for most users unless an extremely heavy data consumer requires an unlimited‑style plan, which Supera link does not currently supply.
