eSIM Japan
Reliable internet access is essential when traveling in Japan. Roaming with your home operator is expensive, and buying a local physical SIM card upon arrival takes time. A virtual eSIM solves these problems: you purchase and activate a data plan remotely, without swapping your physical SIM, while keeping your primary number active for calls.
