Wiiline does not provide eSIM plans for Japan that include a phone number or SMS capability. The provider offers only data‑only eSIMs for travelers visiting Japan.
Travelers who need voice or messaging can use VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection. However, some destinations may block or restrict access to specific apps or VoIP services, so it is advisable to verify that the apps you rely on are available in Japan before purchasing a Wiiline eSIM.
