Is using EastESIM a more straightforward process than buying a local SIM card at Japan's Narita (NRT) or Haneda (HND) airports? Is ID required for EastESIM?

Yes, EastESIM offers a significantly smoother arrival experience. Purchasing a physical SIM card at Narita (NRT) or Haneda (HND) airports (from providers like SoftBank or NTT Docomo) often involves navigating kiosks, waiting in queues, and a mandatory passport registration process. 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.
