ESIM.DOG does not provide any plan that offers a truly unlimited high‑speed data allowance for South Korea. The only plan that uses the word “Unlimited” actually delivers 1 GB of high‑speed data before the speed is throttled to 384 kbps.
Instead, ESIM.DOG sells fixed‑data eSIMs that give higher amounts of data while keeping standard 5G or LTE speeds. Examples include a 50 GB plan valid for 30 days costing $20.02 USD, a 30 GB plan for 30 days at $30.99 USD, and a 20 GB plan for 30 days at $10.01 USD. These fixed‑data options may be more cost‑effective for most travelers than an “unlimited” plan that throttles after a very small data limit.
