Wiiline eSIM Data Plans for South Korea

Wiiline does not provide a truly unlimited data eSIM for South Korea. All of its plans labelled “Unlimited” actually contain a fixed data allowance—either 1 GB per day or 5 GB per day—and after that limit the speed is throttled (to about 0.384 kbps in most cases).

If a user prefers a high‑capacity option without a hard limit on speed, Wiiline offers larger fixed‑data plans such as a 1 GB per day plan for 20 days priced at $18 USD or a 5 GB per day plan for 10 days priced at $17 USD. These alternatives provide generous bandwidth for the chosen validity period but are not unlimited.

Wiiline does not provide eSIM plans with a local phone number or SMS capability for South Korea; all of its offerings in this destination are data‑only. Travelers can still use popular VoIP services such as WhatsApp, Telegram, or iMessage over the Wiiline data connection to make calls and send messages without a local phone number.

Wiiline offers a mix of single‑country and multi‑country eSIM plans that can be used in South Korea. There are 44 single‑country plans and 35 multi‑country plans that include South Korea within their coverage network.

The plans span a price range from roughly $1.26 to $206 and provide data caps from 490 MB up to 100 GB, with validity periods that can last from a single day to 365 days. Wiiline supplies both fixed‑data‑cap plans, where a set amount of data is allocated for the whole validity period, and daily data‑cap plans, which allow data to be accumulated and used day by day. This gives travelers flexibility in how they spend their data while visiting South Korea.
