Collaboration with Welcome Suica Mobile

In addition, customers can purchase the Japan SIM through a dedicated link in the Welcome Suica Mobile app, a service provided by East Japan Railway Company (JR East). This app aims to facilitate a seamless travel experience for international tourists by allowing them to manage their transportation needs without needing to visit ticket counters or machines. Through this partnership, users can expect a simplified connection as they navigate throughout Japan.
