4S eSIM eSIM Data Plans for South Korea

No, 4S eSIM does not provide a true unlimited data plan for South Korea. Every plan listed has a specific data cap that applies to high‑speed data. Travelers can choose from fixed data plans such as the 50GB 30‑day plan or the 20GB 5‑day plan, which offer large amounts of data but still have a hard limit. If a user requires more data, they can purchase additional fixed‑data packages or add a pay‑as‑you‑go option, but no plan offers unlimited high‑speed data.

4S eSIM does not provide a South Korea eSIM plan that includes a phone number or SMS capability. All South Korea eSIM offerings from 4S eSIM are data‑only. Travelers who need voice or text communications can use VoIP apps such as WhatsApp, Telegram, or iMessage over the data connection; however, some destinations may block or restrict specific apps, so you should verify that the apps you rely on are accessible in South Korea before buying.

In its full catalogue the provider lists 57 single‑coverage data plans and 162 multi‑country data plans, both of which cover South Korea as part of the offering.

Plans are divided into daily data‑cap products (52 in total) and fixed data‑cap products (167), allowing customers to choose between a set amount of data for a set period or a daily allowance that can be used flexibly.
