abesteSIM eSIM Data Plans for South Korea

abesteSIM does offer unlimited data eSIM plans for South Korea. The plans cover a validity range of 1 to 30 days, with prices ranging from $3.25 USD for a one‑day plan to $66.81 USD for a 30‑day plan. All unlimited plans provide 4G, 5G, and LTE coverage, with a maximum speed of 5000kbps; speeds may be throttled after heavy usage in accordance with a fair usage policy.

Because speeds can be reduced after extensive use, travelers who need consistent performance are advised to contact abesteSIM directly to confirm whether a fair usage policy applies to the specific plan they intend to purchase and to discuss the typical amount of data available at normal speed.

abesteSIM does not provide an eSIM for South Korea that includes a phone number or SMS capability. Only data‑only plans are available from this provider. Travelers who need voice or messaging can use popular VoIP applications such as WhatsApp, Telegram, or iMessage, which operate over the data connection provided by the eSIM.

abesteSIM provides data plans that cover South Korea in both its single‑country and multi‑country catalogues. In the single‑country segment there are 46 plans that include South Korea, while the multi‑country section offers 131 plans that cover the country as part of broader itineraries. These plans vary from a data cap of 200 MB to unlimited data, and are priced between about $0.96 and $123.71. Some plans allow tethering, while others may have reduced speeds or throttling after a certain amount of data is used.
