JamboSim eSIM Data Plans for South Korea

JamboSim does not provide a truly unlimited data eSIM for South Korea. All of its plans for the country have a fixed data allowance that is capped at 3 GB per day for the “Unlimited”‑named plans, after which the speed is throttled to about 1 Mbps. Travelers who need more data can choose from the fixed‑data plans, such as the 50 GB/7 days plan or the 100 GB/180 days plan, which offer larger data bundles for a set validity period. These fixed plans can be more cost‑effective for users who anticipate heavy data usage.
