No. An eSIM can be installed only once, and it locks to the first device it is installed on. It cannot be moved to another phone, re-scanned, or reinstalled afterward, and it is non-refundable once installed. Please install your eSIM on the device you plan to keep using. If you are switching devices and need help, contact our support team.

No, this CheapESIM plan is designed as a data-only eSIM and does not include a local Korean (+82) phone number. This is an important distinction for travelers in South Korea, as many local services, including restaurant waitlist systems like CatchTable and certain apps like Naver, often require a local number for registration or verification. Our eSIM provides high-speed data for all your internet needs – navigation, messaging, and app usage – but if a local number is essential for your trip, you might need to consider an alternative or supplementary service. We focus on providing the best value for mobile data connectivity.

Yes, CheapESIM offers a significantly more streamlined and private experience than purchasing a physical SIM at Incheon Airport (ICN). While local SIMs from providers like KT or SKT are available, they often involve considerable waiting times, especially during peak arrivals, and necessitate a mandatory passport registration process. Our eSIM is entirely digital, allowing for activation before you even depart, and requires no ID registration. This means you bypass queues and paperwork, gaining instant, hassle-free internet access upon landing in South Korea. It’s the optimal choice for travelers seeking efficiency and privacy without compromising on value.

This ensures uninterrupted connectivity for planning your next move, entertainment, or staying in touch, making CheapESIM an excellent value choice for seamless travel across the country.

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.

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.
