Yes, RedEx eSIM offers an unlimited data eSIM that can be used in South Korea. The only plans labeled “unlimited” cover one day or three days. The 1‑day unlimited plan is priced at $5.01 USD and the 3‑day unlimited plan at $15.12 USD. Both plans allow tethering, but the data cap is unlimited only up to the point where the fair‑usage policy becomes active; after heavy usage speeds may be throttled to a lower rate. If you are concerned about potential speed restrictions, you should contact RedEx eSIM directly to confirm whether a fair‑usage policy applies and to learn the typical amount of data available at normal speed.
RedEx eSIM offers a South Korea eSIM that includes a phone number and full SMS capabilities. The standard plan provides 20 GB of data for 30 days at a price of $35.89 USD and allows both inbound and outbound voice calls as well as inbound and outbound SMS. The phone number that comes with the plan uses the local South Korean dialing code +82, so you receive a local number in South Korea. Other bundled plans are available that include numbers with dialing codes +61 (Australia) and +971 (UAE) but they also support inbound and outbound calls and SMS in the same way. Travelers who need specific local or international number details should confirm the exact functionality with RedEx eSIM before purchase.
RedEx eSIM offers a total of 106 single‑country plans and 347 multi‑country plans worldwide. These plans include 348 fixed‑data‑cap options and 105 daily data‑cap options, covering a price range of $1.63 to $545.92 and a data range from 100 MB up to unlimited. The dataset, however, does not provide a country‑specific breakdown, so the exact number of South Korea‑only plans cannot be determined from the available information.
