SimOptions eSIM Data Plans for Japan

SimOptions does not provide an unlimited data eSIM for Japan. Travelers looking for data coverage in Japan can instead choose from fixed‑data plans such as the Japan 30GB plan, which offers 30GB of data valid for 25 days at $24.90 USD, or the Japan 20GB plan that gives 20GB for 25 days at $19.90 USD.

Selecting a fixed‑data plan may be more cost‑effective for most users, while an unlimited plan would only be justified for extremely heavy data consumers.

SimOptions does not offer any eSIM plans for Japan that include a local phone number or SMS capability. All of the available plans are data‑only, providing a high‑speed internet connection without built‑in voice or text messaging features. Travelers who need to make calls or send messages can use VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection, which are fully functional without a separate phone number.

SimOptions currently offers 7 single-country data plans specifically for Japan. These plans range in price from approximately $4.50 to $24.90 and provide data allowances between 1GB and 30GB. Plan validity periods vary from 5 to 25 days. SimOptions does not currently list any multi-country plans that include Japan as part of their coverage. These plans generally offer a fixed data amount for use during the validity period.
