WonderConnect eSIM Data Plans for Japan

WonderConnect does not provide any unlimited data eSIM plans for Japan. Travelers who need a substantial amount of data can choose from the fixed data plans that are available. For example, a 50GB plan can be purchased for 30 days at $45.00 USD, while a 20GB plan is priced at $21.32 USD and a 10GB plan at $14.04 USD. All of these plans include tethering, but the data allowance is capped. Choosing a fixed data plan may be more cost‑effective unless a user expects to consume data at an extremely high rate.

WonderConnect does not offer any eSIM plans for Japan that include a phone number or SMS capability. All plans sold by the provider for the country are data‑only, without inbound or outbound voice or text services.

Travelers who need voice or messaging can use VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection to make calls and send messages without a traditional phone number.

WonderConnect provides a range of Japan‑only eSIM options as well as regional bundles that cover Japan. The catalog lists six single‑country plans tailored for Japan, and five multi‑country plans that include Japan in their coverage. For the Japan‑only bundles, data caps span from 1 GB up to 50 GB, with prices between USD 3.50 and USD 150, depending on the duration—between 7 and 30 days. The multi‑country packages offer similar flexibility; their caps can also reach up to 50 GB, while the prices remain within the same USD 3.50 to USD 150 range. The plans are available as set data packages, meaning customers receive a fixed data allowance for the entire validity period, rather than a daily cap system.
