Flysimio eSIM Data Plans for Japan

Flysimio does not provide an unlimited data eSIM for Japan. The available Japan eSIMs are fixed‑data plans that specify a clear data cap and validity period. For example, the Japan 50GB 30Days plan gives 50GB of 5G data for 30 days at $42.50 USD, and the Japan 50GB 180Days plan offers the same 50GB for 180 days at $70.00 USD. Choosing a fixed‑data plan can be more cost‑effective for most travelers, unless a user is an extremely heavy data consumer.

Flysimio does not provide a Japan eSIM that includes a phone number or SMS capability. The provider offers only data‑only plans for travelers in Japan.

Travelers who need voice or messaging can use popular VoIP applications such as WhatsApp, Telegram, and iMessage over the data connection. However, some destinations may block or restrict access to specific apps or VoIP services, so it is advisable to verify that the apps you rely on are available in Japan before purchasing a plan.

Flysimio offers nine single‑country data plans that cover Japan, and nine multi‑country plans that include Japan as part of a broader regional package. Among the Japan‑focused plans, there is one plan with a daily data cap, while the remaining plans provide fixed data amounts. Prices for these plans range from about $1.75 to $166.25, data caps span from 1 GB to 50 GB, and validity periods vary between 7 and 365 days.
