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.

Travelers should exercise caution and thoroughly check their U.S. mobile plan when visiting Saipan and the Northern Mariana Islands (CNMI). Although a U.S. territory, many standard U.S. carrier plans from AT&T, T-Mobile, or Verizon do not include CNMI in their domestic coverage. You might face exorbitant pay-per-use roaming fees, often several dollars per megabyte, or experience severe speed throttling to unusable 2G/3G. An EastESIM specifically for Saipan or a broader Asia plan offers transparent, affordable data rates, preventing unexpected charges and ensuring you stay connected at high speeds without any surprises.

To provide you with unparalleled speed and coverage in one of the world's most connected nations, your EastESIM in South Korea will connect to the country's leading mobile networks. These typically include top-tier providers like SK Telecom or KT Corporation. These partnerships ensure you receive the fastest and most reliable 4G/LTE and 5G coverage available, whether you're navigating the bustling streets of Seoul, exploring historic sites in Gyeongju, or enjoying the coastal beauty of Busan. EastESIM's commitment to local carrier expertise means you'll experience seamless internet access throughout your Korean adventure.

A specific EastESIM plan purchased for South Korea is valid only within South Korea. If your travel plans include visiting neighboring countries like Japan or China, your South Korea-specific connection will not extend beyond its borders. These are distinct countries with separate telecom networks and regulations. For travelers embarking on a multi-country Asian itinerary, we highly recommend exploring our regional Asia-wide EastESIM plans. These comprehensive packages are designed to provide seamless connectivity across multiple nations, saving you the hassle of purchasing individual eSIMs for each leg of your exciting journey.
