eSimpli eSIM Data Plans for Japan

eSimpli does not provide a truly unlimited data eSIM for Japan. The plans that carry the word “Unlimited” in their name give a fixed allowance of 1GB per day; after that limit the speed is reduced to 1250 kbps, so the data is not unlimited.

Travelers who need more data can choose from eSimpli’s fixed data plans for Japan, such as the 20 GB plan for 30 days, the 10 GB plan for 30 days, or the 5 GB plan for 30 days, all of which are available on 5G. These options offer larger data allowances and may be more cost‑effective unless a user requires truly unlimited data.

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.
