Cheapest & Best South Korea eSIMs: Top 9 Providers Compared
Nine eSIM providers compared on South Korea data prices in USD, with each allowance paired to its validity, showing where Airwaily leads and where a rival undercuts it.
The dated comparison tables below reflect the observation date recorded for each figure and are not a guarantee of current pricing.
How We Compared South Korea eSIM Prices
Airwaily publishes this comparison and sells one of the products in it, so its plans sit beside rival offers throughout. We compared nine selected providers on recorded USD prices for South Korea across ten groups, each fixing an exact allowance or a minimum plus a stay length. A 5 GB plan over 15 days is judged separately from 5 GB over 30 days, since extra validity usually raises the price. Each section names the winner and the size of the gap.
Exactly 1 GB: The Cheapest Entry
Airwaily's 1 GB plan runs 7 days for $0.90, the cheapest 1 GB entry. Ubigi asks $1.80 for 1 day and GigSky $2.39 for a week.

Our South Korea eSIM Verdict
Pick by stay length, not by one headline price. Airwaily leads nine of the ten groups, including $2.45 for 5 GB over 15 days, $5.24 for 10 GB over 30 days and $21.85 for 30 GB over 60 days. Cheaper rival figures elsewhere usually buy fewer days, so read both numbers together. For exactly 50 GB over 30 days, MobiMatter's $23.99 beats Airwaily by $0.87.
How to Read These Prices
Airwaily's retail prices were observed on 11 November 2026 and competitor records on 9 November 2026, all shown in USD; some competitor amounts were converted at source rather than quoted natively. Promotions are already reflected, with no extra discount added. The ten tables take each provider's cheapest paid fixed-allowance offer for the given criteria across nine selected providers, so a low figure may come with a short validity.
