MobileSIM eSIM Data Plans for South Korea

MobileSIM does not provide a truly unlimited high‑speed data plan for South Korea. The only plan titled “South Korea Unlimited data for 10 days” actually allows 3 GB per day; after the 3 GB threshold is reached the speed is throttled to 1000 kbps.

Travelers who need more data can choose one of MobileSIM’s fixed‑data plans. For example, a 20 GB plan is available for 30 days at $32.00 USD, and a 50 GB plan is offered for 90 days at $100.00 USD. These plans give full‑speed data for the entire allowance and are often more cost effective unless a user expects to consume data far beyond the allocated amount.

MobileSIM does not provide eSIM plans for South Korea that include a phone number or SMS capability. Their South Korea offerings are data‑only, so you can use the data allowance for internet access, but calls and text messages must be made through data‑based VoIP apps such as WhatsApp, Telegram, or iMessage.

MobileSIM offers a total of 7 single‑country plans that are valid only in South Korea and 14 multi‑country plans that include South Korea along with other destinations. The provider’s catalog contains 20 fixed data‑cap plans that provide a set amount of data for the duration of the validity period, while 1 daily‑data‑cap plan offers a total amount of data that is distributed evenly across each day of the plan’s validity. Pricing for South Korea plans spreads from roughly $4.50 to $185, with data caps ranging from 1 GB up to 100 GB, giving travelers a broad selection of both budget and high‑volume options.
