nextSIM eSIM Data Plans for South Korea

No, nextSIM does not provide a truly unlimited data eSIM for South Korea. The plans that carry “Unlimited” in their name are fixed‑data plans that offer a set amount of high‑speed data, after which the speed is throttled to 512 kbps or 2000 kbps. For travelers who need larger amounts of data, nextSIM offers fixed‑data options such as the 100GB 30days plan priced at $149.11 USD or the 50GB 30days plan at $84.21 USD. These plans can be more cost‑effective for heavy users while still providing a substantial data allowance.

nextSIM does not provide South Korea eSIMs that include a phone number or SMS capability. The plans it offers for South Korea are data‑only, so travelers will not receive a local South Korean number with voice or text services.

Customers who need phone or text functionality can use VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection, but this may depend on local restrictions. It is advisable to confirm that the specific apps you rely on are accessible in South Korea before purchasing an eSIM from nextSIM.

nextSIM provides 31 single‑country plans for South Korea and 75 multi‑country plans that include South Korea. The available plans vary widely. Prices across all offers range from approximately $3.84 to $1, 278.53, while data caps span from 1 GB up to 100 GB. Some plans are fixed‑data, giving a set amount of data for the validity period, whereas others use a daily data cap, limiting the data available each day. The validity length of these plans also ranges from one day to ninety days, allowing travellers to choose a duration that fits their trip.
