WonderConnect eSIM Data Plans for Japan

WonderConnect does not offer an unlimited data eSIM plan for Japan. Travelers who need a large amount of data can consider fixed‑data options such as the 50GB 30‑day plan priced at $45.00 USD or the 20GB 30‑day plan priced at $21.45 USD. These plans provide substantial data for a set validity and can be more cost‑effective unless the user is an extremely heavy data consumer.

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 eSIM plans that cover Japan, and five multi‑country plans that include Japan. The plans range from a fixed data amount of 1 GB to 50 GB, some offering a daily data cap, with prices spanning roughly $5 to $150. Validity periods vary from seven to thirty days, and most plans allow tethering.
