Korea eSIM prices compared
As of 2026-08-11, the cheapest Korea eSIM we track is 1GB for 3 days at $4.00 on SK (5G), across 19 plans collected from the provider's own product feed. The cheapest plan is rarely the right one, though — a three-day plan expires before most trips end, so the table below ranks against your dates and your data.
Cheapest plan covering 5 days and 3 GB
3 GB · 7 days — $9.00
$1.29 per day on SK (5G). 12 of the 19 plans in the feed are not shown below: they either run out before your trip does, carry less data than you asked for, or cost more than another plan with the same allowance.

the same as average
Now $4.00, against a 7-day average of $4.00 — the lowest we have recorded in that window.
Same trip, next decision
How we pick
We rank on total price, but only among the plans whose validity is at least as long as the trip you entered. Ranking on price alone always puts the shortest plan first, which is the wrong answer for anyone staying longer than it lasts — so plans that run out before your trip ends stay visible but are dimmed, with the reason shown.
Airalo's Korea packages are all unlimited-data, so there is no price-per-GB to compare. That makes cost per day the axis that matters, and it is the column to read.
How a price gets published here
Each price is read from the provider's own page and then read a second time, independently, before it goes up. If the two readings disagree we publish nothing — we do not average them and we do not pick one. The date beside a price is the date of that check, not the date this page was rebuilt.
What we collect, and when
Provider prices are collected once a day and appended to a public history, so we can later tell you whether today is cheap relative to the last 30 days. Until 30 days of history exist we do not make that claim — a “30-day average” computed from 12 days is simply wrong.
Quick answers
How do you rank Korea eSIM plans?
By total price among only the plans whose validity is at least as long as the trip. Ranking on total price alone always puts the shortest plan first, which is the wrong answer for anyone staying longer than it lasts.
How often are these prices collected?
A plan is published only after its price has been checked against the provider’s own page, and the date of that check is shown beside the price. Each check is made twice, independently; if the two readings disagree the plan stays unpublished rather than being averaged or guessed.
Why do you not show whether today is cheap compared to the last 30 days?
Because that claim needs at least 18 of the last 30 days observed. A 30-day average computed from 12 days is wrong, and a wrong number on a price site undermines every other number on it.
