Yes, EastESIM uses local network partners across Asia, so your data traffic is routed through carriers like SK Telecom or KT in South Korea. This means you'll have no issues accessing essential local apps such as KakaoTalk for messaging, Naver Maps for navigation, or banking applications. You'll appear as a roaming user on their network, which is perfectly fine for all standard app usage, ensuring you stay connected and navigate like a local.
