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 Japan eSIM plan that includes a phone number or SMS capability. All eSIMs sold by this provider for Japan are data‑only, meaning they provide high‑speed connectivity but do not support inbound or outbound voice calls or text messages. Travelers who need to communicate while in Japan can rely on data‑based services such as WhatsApp, Telegram, or iMessage, which operate over the internet and do not require a local phone number or SMS functionality.

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.
