No. Genki Mobile’s Japan Travel eSIM is a data-only eSIM and does not include a phone number. This means you cannot make traditional phone calls or send SMS text messages using the eSIM.
However, you can still make calls and send messages using internet-based apps such as WhatsApp, Messenger, Instagram, LINE, and similar services.
If you are using an iPhone, you can also use iMessage and FaceTime over the internet.
