South Korea eSIM: daily caps, throttling and hotspot, brand by brand
Of 23 travel eSIM brands with a rule that applies to South Korea, 10 publish a daily full-speed allowance, 9 publish the speed you drop to afterwards and 4 state a hotspot rule. 2 rows rest on dated customer reports rather than the brand's own page and are marked unverified. Every number links to its source with the date it was observed; last review 2026-10-19.
South Korea has some of the fastest mobile networks in the world (SK Telecom, KT, LG U+), so an unlimited travel eSIM there can burn through a daily full-speed bucket in a couple of hours of video. The after-cap speed and the hotspot rule are what separate the brands. The table shows what each publishes for Korea, Asia or worldwide.

What to watch for in South Korea
Korean apps (maps, taxis, payments) are data-light; what empties a bucket is video and photo backup.
Hotspot is often capped lower on Asia rows than Europe rows from the same brand.
Brands without a Korea row are governed by their Asia or global rule.
