UPeSIM eSIM Data Plans for South Korea

UPeSIM does not offer an unlimited data eSIM for South Korea. Instead, travelers can choose from fixed‑data plans, such as the 10GB 30‑day or the 5GB 10‑day options, which provide high‑speed data on 4G and 5G networks across South Korea. These fixed‑data plans can be more cost‑effective, especially for heavy data users, unless a truly unlimited data experience is required.

UPeSIM does not offer South Korea eSIM plans that include a phone number or SMS capability. The provider sells only data‑only eSIMs for South Korea. Travelers can use internet‑based services such as WhatsApp, Telegram, or iMessage over the data connection to make calls and send messages without needing a local phone number or SMS.

UPeSIM offers three single‑country plans and three multi‑country plans for use in South Korea. The single‑country plans provide a specific data volume, ranging from 1 GB to 10 GB, with validity periods of 7 to 30 days. The multi‑country plans follow the same structure, offering the same data caps and validity lengths but covering several countries in addition to South Korea. Prices for all UPeSIM plans in South Korea start at approximately $3.51 and rise to about $46.97, depending on the chosen data amount and validity. All plans allow tethering, giving users the flexibility to share data with other devices.
