Ohayu eSIM Data Plans for South Korea

Ohayu does not provide any unlimited data eSIM plans for South Korea.
Travelers who need a larger data allowance can choose from fixed plans such as the 50GB 30 days plan priced at $76.79 USD or the 25GB Monthly plan costing $49.49 USD. These fixed plans offer 5G coverage within South Korea (and, in the case of the 25GB monthly plan, additional coverage in 105 other countries). Choosing a fixed data plan can be more cost‑effective for most users unless extremely heavy data consumption is anticipated.

Ohayu does not offer a South Korea eSIM that includes a phone number or SMS capability. The provider only sells data‑only eSIM plans for travel in South Korea and currently does not provide telephony services in that destination.

Because a phone number and SMS are not available, travelers who need to communicate while abroad can rely on popular VoIP applications such as WhatsApp, Telegram, and iMessage, which operate over a data connection and allow voice calls and messaging without a traditional phone number.

Ohayu supplies a total of ten data packages for South Korea, comprising six single‑country options and four multi‑country bundles that include South Korea.
The single‑country plans provide data allocations between 1 GB and 50 GB with validity durations spanning one to thirty days, and prices range from roughly $0.49 to $76.79.
The multi‑country bundles offer the same overall data and validity ranges, allowing tethering and are typically aimed at users who will visit several countries during a short trip.
