MobileSIM eSIM Data Plans for South Korea

MobileSIM does not have a truly unlimited high‑speed data eSIM for South Korea; all plans that carry an “Unlimited” name actually provide 3GB per day of high‑speed data and then reduce the speed to 1000kbps after the daily limit is reached. Travelers who need a fixed amount of data may choose plans such as the 30‑day South Korea 20GB plan for $30.00 USD or the 180‑day Asia 100GB plan for $89.00 USD, which offer larger data allowances without the speed throttling that applies to the “Unlimited” options.

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.
