Yesim eSIM Data Plans for Japan

Yesim provides unlimited data eSIM plans for Japan, with validity options from 1 day to 30 days. Prices for these Japan‑only plans range from $4.27 USD for a 1‑day pass to $51.91 USD for a 30‑day plan, all delivered over 5G and allowing tethering. The plans state that speeds may be throttled after use.

Because the plans are unlimited, a Fair Usage Policy applies, which can reduce speeds after heavy usage. If a traveler is concerned about potential speed restrictions, it is advisable to contact Yesim directly to confirm whether the Fair Usage Policy is in effect and to learn the typical amount of data that remains available at normal speed.

Yesim does not offer any Japan eSIM plan that includes a phone number or SMS capability. Travelers can only purchase data‑only eSIMs from Yesim for Japan. Virtual or VoIP applications such as WhatsApp, Telegram, and iMessage can usually be used over the data connection for voice and text communication, but availability of these services may be limited or blocked in Japan. Travelers should verify that the specific apps they intend to use are accessible in Japan before purchasing a Yesim eSIM plan.

Yesim offers 9 single‑country data plans that cover Japan and an additional 25 multi‑country plans that include Japan. The plans vary in validity from 1 to 365 days and in data from 1 GB up to unlimited, with prices ranging roughly from $4.30 to $231.01. Some of the offerings are fixed data bundles, while others impose a daily data cap; the overall price and data ranges are similar across both types.
