WonderConnect eSIM Data Plans for Japan

WonderConnect does not offer an unlimited data eSIM plan for Japan. Instead, the provider offers several fixed‑data options, including a 50GB plan for 30 days priced at $40.50 USD, a 20GB plan for 30 days at $21.45 USD, and a 10GB plan for 30 days at $16.00 USD. Choosing a fixed‑data plan can be more cost‑effective for most travelers, unless one expects to use data at an extremely high volume. All available Japan plans include tethering, work on 2G, 3G, and 4G networks, and are valid for 30 days.

WonderConnect does not provide Japan eSIM plans that include a local phone number or SMS capability. Only data‑only eSIMs are available from this provider. Travelers can still use VoIP applications such as WhatsApp, Telegram and iMessage over the data connection for voice and text communication.

WonderConnect offers six single‑country data plans and five multi‑country options for travelers to Japan. Prices across the portfolio range from about $5 to $135, with data limits spanning from 1 GB to 50 GB, and validity periods of 7 to 30 days.
