MobineX does not provide a truly unlimited high‑speed eSIM for South Korea. The plans labeled “Unlimited” actually come with a fixed data allowance of 1 GB or 5 GB; once the cap is reached, speed is throttled to 128 kbps or 1024 kbps respectively (as indicated in the plan features). For travelers who need more data, mobineX offers several large fixed‑data options, such as 100 GB for 180 days at $168.00 USD or 50 GB for 30 days at $94.50 USD, which provide full‑speed data without any throttling after the allowance is reached. These fixed plans can be more cost effective for those who consume more than a few gigabytes of data.
