Flysimo eSIM Data Plans for Japan

No, Flysimo does not offer unlimited data eSIM plans for Japan. Instead, Flysimo provides fixed data plans such as the Japan 50GB 30Days (IIJ) and the Japan 50GB 180Days, both of which include the option for tethering and are valid throughout Japan. Choosing a fixed data plan can be more cost effective for most travelers, unless an extremely heavy data consumer requires an unlimited option.

Flysimo does not offer any Japan eSIM plan that includes a local phone number or SMS capabilities. Their Japan packages are purely data‑only, so travelers cannot make or receive standard phone calls or text messages through the eSIM. For voice and messaging needs, users can rely on internet‑based applications such as WhatsApp, Telegram, or iMessage, which work over the data connection.

Flysimo’s catalog for Japan includes 16 single‑country data plans and 46 multi‑country options that cover the country as part of a broader coverage package.
The single‑country plans vary from 1 GB up to 50 GB of data and run for 1 to 365 days, with prices spanning roughly $2.56 to $130.92.
Multi‑country plans offer the same range of data and validity but bundle Japan with a selection of other destinations, and many allow tethering.
Overall, users can choose from a wide price and data spectrum that fits short‑term stays or longer, multi‑country travel itineraries.
