A South Korea eSIM is a virtual SIM card that connects you instantly to South Korean mobile networks (SK Telecom, KT Corporation, LG U+) without a physical card. Plans start at $4.50 for 1 GB, up to $47 for unlimited.
Do you really need an eSIM? South Korea is not in the European Union: no free EU roaming. International roaming fees are very high ($5-10/MB). An eSIM is therefore essential to avoid astronomical bills.

South Korea is not a member of the European Union. No free roaming applies. French carriers typically charge $5-10 per MB in South Korea, which can quickly generate bills of several hundred euros for just a few days of travel.
South Korea has exceptional 4G/5G coverage (99.9%), among the best in the world, even in the most remote rural areas, thanks to three major carriers:
| Carrier | Coverage | 5G | Used by |
|---|---|---|---|
| SK Telecom | 99.9% | Yes | Airalo, Ubigi |
| KT Corporation | 99.5% | Yes | Holafly, GoMoWorld |
| LG U+ | 99.3% | Yes | Saily |
South Korea has one of the best 5G infrastructures in the world, with extensive 5G coverage in all major cities.
Compatibility: iPhone XS+, Samsung S20+, Pixel 3+, Xiaomi 12+, OnePlus 8+

For all travelers to South Korea, an eSIM is essential: no free EU roaming, prohibitive roaming fees ($5-10/MB).
Our recommendation: Airalo 10 GB at $14 with code ESIMP15 offers the best value on the SK Telecom network (South Korean leader).
For heavy users: Holafly unlimited eliminates any overage stress.
