Billion Connect eSIM Data Plans for South Korea

Yes, Billion Connect offers unlimited data eSIM plans for South Korea. The plans range from 1 day to 30 days in validity and cost between $3.89 USD for a 1‑day plan and $59.79 USD for a 30‑day plan. Each unlimited plan includes tethering, and coverage is available on 3G, 4G, and 5G networks.

Because the data cap is unlimited, speeds may be throttled after heavy use under a Fair Usage Policy. If you need confirmation on whether this policy applies to a specific plan or how much data remains at normal speed, it is advisable to contact Billion Connect directly.

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 offers 49 single‑country data plans and 59 multi‑country plans that include South Korea. The available plans range in price from about $0.83 to $169.03 and in data from 500 MB to unlimited. Plans are split into two main types: daily data cap plans, which reset each day and number 35, and fixed data cap plans, which offer a set amount of data for the full validity period and number 73. This structure gives travelers a broad spectrum of options, from low‑cost, short‑term packages to high‑cap, long‑term plans.
