The usual Korea eSIM trap isn’t “no signal”—it’s this:
Three plans all say unlimited, but IP, speed policy, and app support are completely different.
This guide compares Jeko’s three tiers: SK native true-unthrottled, starter travel, and budget light.
(Carriers: SKT / KT. Data estimate: how much data. Catalog: Korea eSIM.)
Bottom line
- Typical Seoul / Busan / Jeju → starter travel
- Korea IP, true-unthrottled, heavy hotspot/video, or optional number → SK native
- Tightest budget, short trip, no ChatGPT/TikTok need → budget light
Comparison table
| Plan | Network / IP | Speed policy | Number | Apps |
|---|---|---|---|---|
| SK native | SKT native · Korea IP | True-unthrottled high speed | Optional +010 (eKYC) | ChatGPT, TikTok listed |
| Starter | LG U+/SKT roam · Singapore IP | ~10 Mbps after ~1GB daily | Data only | ChatGPT, TikTok, Gemini listed |
| Budget | SKT/LGU+ roam · Hong Kong IP | Unlimited (not native true-unthrottled) | Data only | Gemini/hotspot; no ChatGPT/TikTok |
When to upgrade to SK native
- You want Korea local IP
- Heavy hotspot, meetings, high-quality uploads
- Optional +010 number (and you’ll complete eKYC rules)
Why starter is the sweet spot
- Dual-network roaming
- ~10 Mbps after the daily high-speed bucket for typical travel apps
- ChatGPT/TikTok listed—more complete than budget
- No eKYC for data-only use
Always follow the live product page for eKYC, days, and app labels.
Pick your tier, then open Jeko Korea eSIM—most travelers start with starter travel; upgrade to SK native only when you need local IP or true-unthrottled headroom.
