Lowest marks the cheapest listed price for the same period. Data allowance differs by plan.

Before you go (must-read)
- eSIM support? Dial *#06# for EID. Phone must be unlocked. Some models (Pixel, OPPO) may be restricted.
- When to buy? Online before departure is easiest. Airport counters at Incheon, Gimpo, Gimhae also available.
- Data vs voice? Maps/KakaoTalk/translate only = data-only. Local calls/010 needed = Data+Voice plan.
- Activation timing? Wi-Fi required. Many plans start the clock at first data use. Some must activate within 60 days of purchase.
- Do not delete Do not casually delete the eSIM—many plans cannot be reissued after deletion.
ID verification (ARC) · Data vs voice
Short-term tourists and long-term residents (ARC) need different products.
Tourist eSIM (passport)
Short visits, passport-based. Enough for maps, KakaoTalk, translate.
- PASS / banking / gov ID usually not available
- Data-only is most common and cheapest
- Need 010/voice? Data+Voice plans (often airport/carrier)
- Passport + fixed period, no ARC needed
Resident / MVNO (ARC)
Long stay with ARC. For Korean life and ID verification.
- PASS etc. possible on ARC postpaid/MVNO
- Data + voice (010) recommended for long stays
- Tourist eSIM cannot run banking/PASS apps well
- Often needs ARC + payment method
When something goes wrong
If you cannot connect, install over airport Wi-Fi first and do not delete the eSIM casually.
