💡 Pro Tip for South Korea

South Korea offers the world's most advanced mobile infrastructure with comprehensive 5G coverage, even in subway tunnels and mountain areas. The country is extremely digitized - you'll need data for everything from ordering coffee to entering buildings. Download Naver Maps and KakaoMap before arrival as Google Maps has limited functionality. Most Koreans use KakaoTalk for messaging, which works perfectly with your eSIM. The four seasons bring different travel experiences, but your connection remains excellent year-round. Korea's cashless society means mobile data is essential for payments and daily transactions. PC bangs (internet cafes) are everywhere if you need a desktop, but your mobile 5G is often faster. Language barriers are easily overcome with translation apps powered by fast data. Night owls rejoice - Korea's 24-hour culture means consistent network performance at any hour.
