ChillaxSIM eSIM Data Plans for South Korea

ChillaxSIM does not provide a true unlimited data eSIM for South Korea. The plans that include “unlimited” in their name limit data to 1 GB per day, and once that daily allowance is reached the speed is throttled to 5000kbps.

Instead ChillaxSIM offers fixed‑data plans that may be more cost effective for most travelers. Examples include a 50 GB plan for 30 days at $37.84 USD, a 30 GB plan for 30 days at $24.30 USD, and a 20 GB plan for 30 days at $17.53 USD. All of these plans provide high‑speed 5G access and allow tethering, with reduced speed applied after the data limit is used.

ChillaxSIM does not provide South Korea eSIM plans that include a phone number or SMS capability. Only data‑only eSIMs are available for this destination. Travelers can still use VoIP applications such as WhatsApp, Telegram, and iMessage over the data connection, but they should confirm that these services are accessible in South Korea before purchasing, as some destinations may block or restrict VoIP apps.

ChillaxSIM provides a total of 31 single‑country data plans for South Korea, offering a range of fixed data caps that vary from 1 GB to 50 GB and a daily‑cap option that suits travelers who need a flexible allocation. In addition, the provider offers 5 multi‑country plans that also cover South Korea, allowing users to add additional destinations to a single eSIM profile. Plan prices start at around $2.86 and can rise to approximately $84.43, depending on the data size, validity period, and whether the plan includes daily data limits or a fixed data cap. This gives travelers a wide selection of pricing and data options to choose from when planning a trip to South Korea.
