MobileSIM eSIM Data Plans for South Korea

MobileSIM does not provide a genuinely unlimited data eSIM for South Korea. All plans marketed with “Unlimited” in their name only offer 3 GB of high‑speed data each day; once that daily quota is reached the speed drops to 1000 kbps.

If a user needs more unrestricted data, MobileSIM offers fixed‑data alternatives. For example, a 20 GB plan for 30 days costs $32.00 USD, and a 100 GB plan for 180 days is available for $89.00 USD. These options can be more cost‑effective, especially for travelers who consume data heavily but do not require unlimited usage.

MobileSIM does not provide an eSIM that includes a local phone number or SMS capability for South Korea. The provider offers only data‑only plans, so travelers using a MobileSIM eSIM in South Korea will need to rely on internet‑based applications—such as WhatsApp, Telegram, or iMessage—to make calls and send messages.

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.
