Roamify eSIM Data Plans for South Korea

Roamify does provide unlimited‑data eSIMs that cover South Korea.
The plans start at $3.00 USD for a single day and rise to $85.00 USD for a 90‑day period, with several validities in between (3, 5, 7, 10, 15, 20, 25, 30, 60, 90 days). Every South Korea‑only unlimited plan supports tethering and allows use of the network at 4G or 5G speeds, although the provider notes that speeds may be throttled after heavy usage under a fair‑usage policy. If a user wants to confirm how much data can be used at normal speed or whether a specific fair‑usage threshold applies, it is best to contact Roamify directly.

The plans vary widely in price, from about $2.00 up to $140.00, and the data caps range from 1 GB to unlimited; validity periods span 1 to 365 days. Some plans allow tethering, though the network speed may be throttled.
