This specific Truly Roaming eSIM plan is exclusively valid within South Korea. For digital nomads planning multi-country adventures across Asia, it's crucial to understand that your connectivity will cease if you travel from Seoul (ICN) to, say, Tokyo (NRT) or Taipei (TPE). For seamless transitions between countries like Japan or Taiwan, we highly recommend exploring our regional Asia eSIM options, which provide continuous coverage across multiple destinations without needing to switch plans.
