esimzon eSIM Data Plans for Japan

esimzon provides unlimited data eSIM plans for Japan. The available unlimited options run from 4 days to 15 days, with prices ranging from $9.90 USD for the 4‑day plan to $25.00 USD for the 15‑day plan. These plans are marketed as unlimited, but the provider notes that speeds may be throttled after heavy usage under a fair usage policy. Travelers who are concerned about potential speed restrictions should contact esimzon directly to confirm how data is handled at normal speed and what typical usage thresholds apply.

esimzon does not provide a Japan eSIM plan that includes a phone number or SMS capability. The company offers only data‑only eSIMs for travelers visiting Japan, so there is no telephone dialing code, inbound or outbound voice service, or SMS service available from esimzon. Travelers who need to make calls or send messages can use data‑based applications such as WhatsApp, Telegram or iMessage, which work over the data connection without requiring a local phone number or SMS functionality.

esimzon provides nine single‑country data plans for Japan and one multi‑country plan that includes Japan. Prices start around $4 and go up to $28, while data limits range from 3 GB to unlimited. Some plans may experience speed throttling.
