EastESIM plans for Japan are optimized for data, and as such, they are data-only and do not include a local +81 phone number. Obtaining a voice-enabled SIM as a tourist in Japan can be quite challenging due to strict local regulations. However, for restaurant or tour reservations, many establishments in Japan now offer online booking systems (like TableCheck or directly via Google Maps). For voice communication, you can always use popular apps such as LINE, WhatsApp, or Skype over your EastESIM data connection.
