Roaming in South Korea: questions.

Roaming charges and rules for South Korea, from the carriers’ own prices.

No. EU roaming rules apply in the EU, Iceland, Liechtenstein and Norway; South Korea is outside them, so every carrier sets its own price. None of the 6 EU carriers we track include it in their EU allowance.
