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.

This particular EastESIM plan is exclusively valid for use within Japan. We understand that many travelers to Asia often combine destinations, perhaps visiting Tokyo before heading to Seoul, South Korea, or Taipei, Taiwan. For these types of multi-country journeys, EastESIM offers convenient regional Asia plans that provide seamless data coverage across several countries. This means you won't need to purchase separate eSIMs for each leg of your trip, ensuring you stay connected whether you're exploring Kyoto's temples or Busan's beaches.

Unfortunately, 'Roam Like at Home' benefits from US or UK SIM cards almost never extend to Japan. Post-Brexit, many UK carriers have reintroduced daily roaming fees for non-EU countries, and US carriers typically charge premium rates for international data. Relying on your home SIM in Tokyo, Osaka, or even Hokkaido will likely result in very expensive charges. EastESIM provides dedicated, affordable plans for Japan, leveraging local networks like NTT Docomo or SoftBank to give you reliable, high-speed data without the worry of unexpected bills. It's the smarter way to stay connected.

With EastESIM, you can activate your data plan entirely digitally before you even depart, or immediately upon landing, directly from your phone. There's no physical SIM to swap, no queues, and no ID registration required for activation, letting you hit the ground running in Tokyo or catch your train to Kyoto seamlessly.
