Simbye eSIM Data Plans for Japan

Simbye does not provide a truly unlimited data eSIM for Japan. The plans named “Japan Unlimited” actually have a 2GB/day data cap; after that daily limit is reached the speed drops to 1000 kbps, so the data is not unbounded.

Travelers can opt for fixed‑data plans from Simbye that cover Japan. For example, the Japan 20GB plan lasts 30 days and the Japan 50GB plan remains valid for 180 days. These options give a larger bulk allowance at a predictable cost and can be more economical unless a traveler requires constant, unrestricted high‑speed service.

Simbye offers eSIM plans for Japan that include a phone number and SMS capability. The available options are the Worldwide Orange Holiday 20GB, 50GB, and 100GB plans, each valid for 30 days and priced at $31.99 USD, $49.99 USD, and $59.99 USD respectively.

These plans provide a French phone number with dialing code +33. Calls can be received and made (voice inbound and outbound), and SMS can be sent and received (SMS inbound and outbound). The numbers are not local Japanese numbers, so users should confirm with Simbye if a local Japan number is required.

Simbye offers 9 single‑country plans and 8 multi‑country plans for Japan. The plans range from $2.99 to $69.99 and provide between 1 GB and 100 GB of data, with validity periods from 7 to 180 days. Among the options, three plans feature a daily data cap, limiting the amount of data that can be used each day, while fourteen plans offer a fixed data cap that applies to the entire validity period.
