ChillaxSIM eSIM Data Plans for South Korea

ChillaxSIM does not offer a truly unlimited data eSIM for South Korea. The plans labeled “unlimited” provide a fixed allowance of 1GB per day; after that amount is used, the speed is throttled to 5120kbps. For travelers who need higher bandwidth without daily limits, ChillaxSIM supplies fixed data plans such as the 50GB for 30 days plan, priced at $49.90 USD, and the 30GB for 30 days plan, priced at $32.90 USD. These larger‑data plans allocate a set amount of high‑speed data and then reduce speed to 128kbps once the allocation is exhausted. Selecting a fixed data plan can be more cost‑effective for most users, unless they require continuous high‑speed data beyond the daily caps of the “unlimited” options.

ChillaxSIM does not provide a South Korea eSIM that includes a phone number or SMS capability. Their South Korea offerings are limited to data‑only plans, so travelers cannot receive calls or text messages on an active phone number. For voice and messaging needs, users typically rely on VoIP applications such as WhatsApp, Telegram, and iMessage that work over the data connection.

ChillaxSIM offers a total of 43 distinct data plans that cover South Korea, broken down into 38 single‑country plans and 5 multi‑country plans that include South Korea among other destinations. The single‑country options give you a fixed data amount ranging from 1 GB to 50 GB, while the multi‑country bundles allow a daily data cap so you can use the same plan across several countries in the region. Prices across all available plans span from as low as $2.90 up to $69.90, giving travelers a broad choice of budget and data‑cap ranges to suit different usage needs.
