No! This is a crucial point for travelers. While South Korea is a highly connected nation, it is not part of the EU and is generally not included in standard 'free roaming' benefits from US (like AT&T, T-Mobile) or UK (like Vodafone, O2) domestic plans. Most home carriers will impose substantial daily fees or per-MB charges for data usage. An EastESIM plan specifically designed for South Korea provides a far more economical, transparent, and hassle-free way to stay connected, whether you're in Seoul or exploring Busan.
