SimSmash eSIM Data Plans for South Korea

SimSmash does not offer a truly unlimited data eSIM for South Korea; all plans have a specified data cap. However, the provider does have high‑capacity fixed data plans for the country. For example, the South Korea 50GB for 30 days plan gives 50GB of high‑speed data over a month, and the South Korea 20GB for 30 days plan offers 20GB over the same period. These fixed data plans can be more cost‑effective for travelers who need a large amount of data without the per‑day price of the daily unlimited offerings.

SimSmash does not offer South Korea eSIM plans that include a phone number or SMS capability. Travelers who need a local number for calls or text messages will need to look at other providers that supply telephony services. However, callers can still use VoIP applications such as WhatsApp, Telegram, and iMessage over the data connection. Because some destinations may restrict or block certain apps, users should check that the services they rely on work in South Korea before purchasing a data‑only eSIM from SimSmash.

SimSmash offers 12 single‑country data plans that cover South Korea and 18 multi‑country plans that include the country within their coverage list. The available plans range in price from $0.89 to $94.99 and provide data caps between 490 MB and 50 GB; some of the options allow tethering.
