Yes, esimzon offers unlimited‑data eSIM plans for Japan. The available options include 4‑day, 7‑day, and 15‑day packages priced at $9.90, $15.00, and $25.00 USD respectively. All of these plans connect over 5G, and the stated “max speed” is 5G. According to the plan details, speeds may be throttled after heavy usage under a Fair Usage Policy. If you are concerned about potential speed restrictions or need clarification on how much data remains at normal speed, you should contact esimzon directly to confirm the specifics.

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 a total of nine distinct data plans for travelers in Japan, comprising eight single country options and a single multi‑country package. The single country plans vary in data allowance from 3 GB up to unlimited and are priced between US$4.00 and US$28.00, with validity periods ranging from four to thirty days. The multi‑country plan offers similar flexibility but covers additional destinations, maintaining the same price and data ranges. Tethering is permitted on several plans, though speeds may be throttled during peak usage.
