MobileSIM eSIM Data Plans for South Korea

MobileSIM does not provide a truly unlimited data eSIM for South Korea. All of its South Korea‑only plans are fixed‑data bundles that offer 3 GB of high‑speed data per day for a set validity period ranging from 3 days to 30 days. After the allotted data is used, the speed is reduced to 1000 kbps. Travelers who need more data can choose larger fixed bundles, such as the 50 GB plans that last 7, 15, or 30 days, or the 100 GB plan that is valid for 180 days. These fixed plans can be more cost‑effective for most users unless they are extremely heavy data consumers.

MobileSIM does not offer any South Korea eSIM that includes a phone number or SMS capability. The plans available from MobileSIM for South Korea are data‑only, so travelers will need to rely on Internet‑based services. Popular VoIP applications such as WhatsApp, Telegram, and iMessage can normally be used over the data connection for calls and messaging, but users should verify that these services are accessible in South Korea before purchasing, as some destinations may restrict certain VoIP apps.

MobileSIM offers 12 single‑country data plans that cover only South Korea and 22 multi‑country plans that include South Korea along with other destinations. The plans are priced from $2.34 to $89.00, provide data between 200 MB and 100 GB, and remain active for 3 to 180 days. Customers can choose between daily data‑cap plans—12 options that may throttle speed after a 1000 MB limit—and fixed data‑cap plans—22 options that deliver a set data amount for the entire validity period.
