WonderConnect eSIM Data Plans for Japan

WonderConnect does not provide an unlimited‑data eSIM for Japan.
Travelers can, however, choose from fixed data bundles such as the 50‑GB plan for $57.50 USD or the 20‑GB plan for $30.00 USD, both valid for 30 days. Selecting a fixed‑data plan can be more economical unless a user expects extremely heavy data use.

WonderConnect does not provide a Japan eSIM plan that includes a local phone number or SMS capability. The available plans from this provider are strictly data‑only, meaning you can use the eSIM for high‑speed internet without receiving inbound calls or texts.

Travelers who need voice or messaging can rely on VoIP applications such as WhatsApp, Telegram, or iMessage, which operate over a data connection and do not require a local phone number or SMS service.

WonderConnect offers six single‑country data plans and five multi‑country plans available for use in Japan. The plans span a price range from about $5 to $150, with data allowances that can be as low as 1 GB or as high as 50 GB per plan. Most plans contain a fixed data amount that does not reset daily, which allows travelers to use the entire allowance over the plan’s validity period of 7 to 30 days. Some of the multi‑country plans also support tethering, enabling the device’s data to be shared with other devices.
