AdventureSIMs does not provide an unlimited data eSIM for Japan. Travelers who need more data can choose from fixed‑data options, such as the Japan 50GB 30 days plan priced at $24.91 USD, which offers 5G connectivity and 30 days of validity. A smaller alternative is the Japan 20GB 30 days plan at $14.95 USD. Fixed data plans can be more cost‑effective unless a user requires very high data usage.
AdventureSIMs does not provide any Japan eSIM that includes a phone number or SMS capability. The service only offers data‑only plans for travelers in Japan. Users who need to communicate over voice or text can use VoIP applications such as WhatsApp, Telegram, or iMessage, which operate over the data connection provided by the eSIM.
AdventureSIMs offers 9 single‑country data plans for Japan and an additional 5 multi‑country plans that include Japan.
