eSimpli eSIM Data Plans for Japan

eSimpli does not provide a truly unlimited data eSIM for Japan. The plans that include “Unlimited” in their name actually allow 1 GB of high‑speed data per day and, once that limit is reached, the speed drops to 1250 kbps. If unlimited usage is required, the provider offers fixed‑data alternatives instead. For instance, the eSIM Japan 20GB 30 days plan costs $32.24 USD, and the eSIM Japan 10GB 30 days plan costs $20.71 USD; these plans give large data allowances at a predictable price and have no speed throttling after the data cap is reached. Choosing a fixed‑data plan can be more cost‑effective unless a traveler is an extremely heavy data consumer.

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.
