eSimpli eSIM Data Plans for Japan

eSimpli does not provide a truly unlimited data eSIM specifically for Japan. The plans that carry the word “Unlimited” in their names actually offer 1GB per day for 5, 7, 10 or 15 days, after which the speed drops to 1250 kbps; these are not hard‑cap unlimited bundles.

Instead, eSimpli offers fixed data plans for Japan that may suit most travelers. For example, a 20GB plan that is valid for 30 days costs about $31.45 USD, a 10GB plan for 30 days is about $21.32 USD, and a 5GB plan for 30 days is about $15.70 USD. These fixed‑data options can be more cost‑effective for users who need a large amount of high‑speed data without the daily limit that applies to the “Unlimited” label.

eSimpli does not offer any Japan eSIM plans that include a phone number or SMS capability. Travelers who purchase an eSimpli eSIM for Japan will receive a data‑only plan only. Voice and text messages can still be sent through popular VoIP apps such as WhatsApp, Telegram, and iMessage over the data connection, but some destinations may restrict or block access to these services, so travelers should verify that the apps they rely on are available in Japan before buying a plan.

eSimpli offers 9 single‑country data plans for Japan and 5 multi‑country data plans that include the Japanese market. The plans are priced between roughly $8 and $110, with data caps ranging from 1 GB to 20 GB. Some plans provide a fixed amount of data that remains available for the entire validity period, while other plans offer a daily data cap that is refreshed every day.
