esimzon eSIM Data Plans for Japan

Yes, esimzon provides unlimited data eSIM plans for Japan. These plans come in four durations—4 days, 7 days, 10 days, and 15 days—with prices ranging from $9.90 USD to $25.00 USD. Each plan is valid for the stated number of days and supports 4G and 5G networks. The plans include tethering but note that speed may be throttled after heavy usage; this is the standard Fair Usage Policy that applies to all unlimited data offerings. If you are concerned about potential speed restrictions, it is advisable to contact esimzon directly to confirm whether the Fair Usage Policy applies to your usage pattern and what amount of data typically remains at normal speed.

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 offers nine single‑country data plans for Japan and one multi‑country plan that also includes Japan in its coverage. The available plans range in price from roughly four to twenty‑eight US dollars and provide data caps from three gigabytes up to unlimited. Validity periods vary between four and thirty days. Single‑country plans are dedicated to use exclusively in Japan, while the multi‑country plan allows the same data to be used across several destinations, giving travelers more flexibility. Some plans permit tethering, but speed may be throttled after a certain threshold.
