MobileSIM eSIM Data Plans for South Korea

MobileSIM does not provide a genuinely unlimited data eSIM for South Korea. The plans that carry “Unlimited” in their name actually allow 3 GB per day of high‑speed data; after that limit the speed drops to 1000 kbps.

Instead, MobileSIM offers fixed‑data options that can be more cost‑effective for heavy users. For example, a 20 GB plan for 30 days costs $30, and a 100 GB plan for 180 days is priced at $89. These plans provide a larger total data allowance without the daily cap that the “Unlimited” plans impose.

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.
