Simbye eSIM Data Plans for Japan

Simbye does not have an unlimited data eSIM available for Japan. All of its plans for Japan are fixed‑data, with caps ranging from 10GB to 50GB.

Travelers can choose between a few notable options: the Japan 50GB 180days plan for $40.00 USD, the Japan 20GB 30days plan for $20.00 USD, and the Japan 10GB 30days plan for $15.00 USD. These fixed‑data plans provide a predictable amount of high‑speed data and are often more cost‑effective unless a user requires an extremely large volume of data.

Simbye does not provide Japan eSIM plans that include a local phone number or SMS capability. Only data‑only eSIMs are available from the provider for use in Japan. Travelers can still use voice and messaging through popular VoIP applications such as WhatsApp, Telegram, and iMessage over the data connection, which allows them to communicate without a phone number or SMS functionality.

Simbye currently offers 6 single-country data plans specifically for Japan, providing coverage within the country only. Additionally, they have 10 multi-country plans that include Japan as part of a broader regional or global coverage area. These plans vary, with options for both fixed data amounts (like 1GB, 5GB, or 10GB total) and daily data allowances. Prices range from approximately $3.00 to $120.00, and data caps range from 1GB to 50GB depending on the selected plan and validity period.
