Mi eSIM eSIM Data Plans for South Korea

Mi eSIM does not offer a truly unlimited high‑speed data eSIM for South Korea. The plans that include “Unlimited” in their name actually provide a fixed amount of data per day – 1 GB for most South Korean plans – and after that amount is used the speed is throttled (384 kbps for South Korea‑only plans). Over the lifetime of the plan the data allowance remains fixed, so the plan is not unlimited.

Travelers who need more extensive coverage can opt for one of Mi eSIM’s larger fixed data plans, such as 50 GB for 30 days or 100 GB for 30 days, which give a sizeable data allowance without the 1 GB per day restriction and without the subsequent speed reduction. These alternatives provide a more cost‑effective solution for heavy data usage when a true unlimited plan is not available.

Mi eSIM does not provide eSIM plans for South Korea that include a phone number or SMS capability. Current offerings from this provider are data‑only plans, so travelers will need to use VoIP applications such as WhatsApp, Telegram, or iMessage for calls and messaging. Because some destinations may block or restrict certain VoIP services, users should confirm that the apps they rely on work in South Korea before purchasing a Mi eSIM plan.

Mi eSIM provides 21 single‑country data plans for South Korea and 47 multi‑country plans that include South Korea.
The plans span a price range from approximately $1.65 to $197.57 and offer data limits between 1 GB and 100 GB, with validity periods from one to 180 days.
Providers use two main plan types: fixed data cap plans give a set amount of data for the full validity, while daily data cap plans distribute a total data allowance across a set number of days, allowing for a daily quota.
