Yesim eSIM Data Plans for Japan

Yesim provides several eSIM plans that offer unlimited data specifically for Japan. These plans range from 1 day up to 30 days of validity, with prices starting around $4.04 USD for a single‑day pass and going up to $63.43 USD for a 30‑day pass. All unlimited Japan plans are pre‑tethering allowed and are delivered on 5G networks.

The unlimited designation is subject to a Fair Usage Policy; after heavy usage speeds may be throttled. If a traveler is concerned about potential speed reductions, it is advisable to contact Yesim directly to confirm the typical amount of data that remains available at normal speed before purchase.

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 13 single‑country data plans for Japan and 25 multi‑country plans that include Japan. The single‑country options range in price from about $4.04 to $229.50, with data caps from 1 GB up to unlimited and validity periods between 1 and 365 days. The multi‑country plans cover Japan as part of a broader itinerary, and they follow a similar price and data‑cap range while allowing travel between several destinations.
