GulfData does not provide a truly unlimited high‑speed data eSIM for South Korea. The plans labeled “Unlimited – 1 day”, “Unlimited – 5 days”, and so on allot 1 GB per day and, after that amount, the speed drops to 512 kbps. Because the speed reduction occurs after the data cap is reached, these plans are not equivalent to an unlimited plan.
If a traveler prefers a larger fixed data allowance, GulfData offers several fixed‑data plans such as the South Korea 50 GB – 30 days plan for $34.00 USD and the South Korea 20 GB – 30 days plan for $16.50 USD. These plans provide a set amount of high‑speed data that must be used within the specified validity period.
