eSIM & internet
Data-only vs. with a Korean number
What works with data-only
| What you want to do | Data-only | With Korean number (010) |
|---|---|---|
| Maps, search, social media, messaging | ✓ | ✓ |
| Calling a taxi by app | Usually ✓ | ✓ |
| SMS verification (sign-ups, bookings) | ✕ | ✓ (some apps still refuse) |
| Food delivery app sign-up | ✕ (most common blocker) | Easier |
| Phone calls (restaurants, hotels) | ✕ | ✓ |
| Price | Cheaper | Higher |

Number plans may need a separate verification step
Example: one plan only verifies between 08:00 and 22:00 Korea time, and works as data-only until verified. Read the plan’s setup steps.

Which one to pick
| You need | Pick |
|---|---|
| Internet only (maps, social, taxi) | A data-only eSIM (e.g. Airalo, Nomad on SKT / LG U+) |
| SMS codes, calls, food delivery | A carrier plan with a 010 number (SKT, KT) |
Prices change often, so they are not listed here. Check each provider’s official page before buying.

Before you fly
- Check your phone is unlocked and supports eSIM.
- Install it at home over Wi-Fi so it works as soon as you land.
