WoWo Sim eSIM Data Plans for Japan

WoWo Sim does not offer any unlimited data eSIM plans for Japan. Travelers who need more data can choose from the available fixed‑data options. Two examples are the Japan 50GB 30Days (IIJ) plan, priced at $35.00 USD, and the Japan 20GB 30Days (IIJ) plan, priced at $16.00 USD. These fixed‑data plans provide a large data allowance and may be more cost‑effective for most users unless an extremely heavy data consumer requires unlimited usage.

WoWo Sim does not provide a Japan eSIM that includes a local phone number or the ability to send or receive SMS. The provider offers only data‑only eSIM plans for Japan, so travelers cannot make or receive regular voice calls or text messages through the carrier. If calling or texting is needed, users can rely on VoIP applications such as WhatsApp, Telegram, or iMessage, which operate over the data connection and do not require an active phone number or SMS capability.

WoWo Sim offers 8 single‑country data plans that cover Japan and 21 multi‑country plans that include Japan. The available options range in price from about $3.50 up to $120, with data allowances anywhere from 1 GB to 50 GB, giving travelers a broad spectrum of possibilities depending on the length of stay and data needs.
