Can I make phone calls with a Japan data eSIM?

Most Japan eSIM plans for tourists are data‑only and do not include a local phone number for traditional voice calls or SMS. However, you can easily make voice and video calls using apps like WhatsApp, FaceTime, Skype, or LINE over your data connection. If you specifically need a Japanese phone number, look for a plan that clearly includes voice service or combine your eSIM with a separate local SIM.
