Billion Connect eSIM Data Plans for South Korea

Yes. Billion Connect sells unlimited data eSIM plans for South Korea. The plans range from 1 day to days of validity and the prices vary from about $2.53 USD for a 1‑day plan to roughly $59.79 USD for a 30‑day South‑Korea‑only plan, with intermediate options such as 3‑day, 5‑day, 7‑day, 10‑day, 15‑day, 20‑day and 30‑day plans. All unlimited plans allow tethering and the data rate can be throttled after heavy use; if you are worried about possible speed reductions, contact Billion Connect to confirm whether a fair‑usage policy applies and the typical amount of data available at normal speed.

Billion Connect does not provide South Korea eSIM plans that include a phone number or SMS capability. The provider sells only data‑only eSIMs for travelers, so there is no inbound or outbound voice or text service attached to the SIM.

If you need to communicate while in South Korea, you can use VoIP applications that work over data, such as WhatsApp, Telegram or iMessage, to make calls and send messages without requiring a local phone number or SMS support.

Billion Connect provides a substantial selection of eSIM plans for South Korea. For this country the carrier offers 49 single‑country plans and 67 multi‑country plans. The single‑country plans generally give customers a fixed data amount that can be used while travelling only within South Korea, whereas the multi‑country plans bundle data for several destinations and allow use in any of those countries during the plan’s validity period. Prices for the South Korean catalogue range from about $0.83 up to roughly $169.03, with data caps that span from 500 MB up to unlimited.
