MoodSIM does not provide a true unlimited data eSIM for South Korea. The plans that carry “Unlimited” in their names only give a set amount of high‑speed data each day; after that daily limit the speed drops to a reduced rate (e.g., 512 kbps, 1 Mbps, or 384 kbps). Once the daily quota is reached, the connection either throttles or the plan expires.
Instead, MoodSIM offers fixed‑data plans that are straightforward to understand. A 20 GB 30 days plan gives 20 GB of high‑speed data for 30 days, while a 50 GB 30 days plan supplies 50 GB for the same period. These fixed‑data plans start as soon as the eSIM connects to a 5G network and are usually more cost‑effective for travelers who do not need very heavy data usage.
