Can I make phone calls with the Japan travel eSIM?

Most Japan travel eSIM plans from EasyAlo are data-only and do not include a local phone number for traditional voice calls or SMS. However, you can easily make calls and send messages using data-based apps like WhatsApp, FaceTime, Skype, or LINE while connected to your eSIM. This setup is usually enough for contacting hotels, ski schools, or tour operators, as many are used to communicating with international visitors through these apps.
