Simsima eSIM Data Plans for South Korea

Simsima does not provide a true unlimited data eSIM for South Korea. All plans that carry the word “Unlimited” in their name give a fixed amount of high‑speed data—3GB per day—and reduce the connection speed to 1000kbps once that daily amount is used. For travelers who need unrestricted data, Simsima offers fixed data plans such as the 50GB 30‑day plan or the 100GB 180‑day plan, which allow users to consume the specified amount of high‑speed data during the validity period before they must purchase additional credit or a new plan. Choosing a fixed data plan can be more cost‑effective for most visitors, especially those who are not extremely heavy data users.

Simsima does not offer South Korea eSIMs that include a local phone number or SMS capability. Travelers can purchase only data‑only plans from Simsima for use in South Korea. Voice and text can still be carried out over the data connection via VoIP applications such as WhatsApp, Telegram, and iMessage. Since some destinations may block or limit specific VoIP services, travelers should verify that the apps they intend to use are accessible in South Korea before making a purchase.

Simsima provides 14 single‑country data plans and 21 multi‑country plans for South Korea. The available plans span a price range from about $1.50 to $178.48 and offer data caps between 100 MB and 100 GB. Some plans feature a daily data cap, while others offer a fixed data amount for the entire validity period.
