This specific CheapESIM plan is exclusively valid within South Korea. It's vital to clarify this for travelers on multi-country Asian trips. If you depart from Seoul (ICN) for Tokyo (NRT) or Taipei (TPE), your connection will cease. To maintain seamless internet across multiple destinations, we strongly advise exploring our dedicated regional eSIM plans, which offer coverage for several countries. CheapESIM's focus is on transparent pricing and clear plan boundaries, helping you budget effectively and avoid unexpected roaming charges when crossing borders, ensuring you always get the best value for your connectivity needs.
