gosimless eSIM Data Plans for Japan

gosimless does not provide an unlimited‑data eSIM plan for Japan. Instead, the provider offers fixed‑data options. For example, a 50GB plan valid for 30 days can be purchased for $22.49 USD, and a 20GB plan valid for 30 days is available for $12.49 or $16.49 USD. Choosing a fixed‑data plan can be a more cost‑effective choice unless a traveler requires very high data consumption that would make a larger data allowance more suitable.

gosimless does not provide Japan eSIM plans that include a phone number or SMS capability. Their available plans are data‑only, allowing only high‑speed internet access. Travelers can still use VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection for voice and messaging without a traditional phone number.

gosimless currently offers 15 single‑country data plans and 14 multi‑country plans for travelers in Japan. The available plans vary between a fixed data amount and a daily data cap, allowing users to choose either a set data bundle for the entire validity period or a daily allocation that adds up over the plan’s duration. Across all offerings, prices range from $3.49 to $116.49 USD, while data cap options span from 100 MB up to 50 GB for the longest‑lasting plans.
