Sim Local eSIM Data Plans for Japan

Sim Local has no plan that provides truly unlimited high‑speed data while you are in Japan. Plans that carry the “Unlimited” label offer 10 GB per day and are valid for a set number of days; once the daily allotment is reached the speed is throttled. If you need higher data volumes, Sim Local offers fixed data plans such as 100 GB for 31 days or 20 GB for 30 days. Selecting a fixed data plan can be more cost‑effective for most travelers unless they expect to use more data than the daily limit in the “Unlimited” offerings.

Sim Local does not provide a Japan eSIM that includes a local phone number or SMS capability. Only data‑only plans are available for travelers to Japan. Users can still make and receive calls, as well as send and receive messages, by using popular VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection, but they should verify that the specific apps they rely on work in Japan before purchasing.

Sim Local provides a choice of 10 single‑country data plans that cover Japan alone, and an additional 9 multi‑country plans that include Japan as one of several destinations. The plans cover a price range from about $4 to $93.50 and a data cap range from 1 GB up to 100 GB, with validity periods spanning 3 to 31 days. The catalog also distinguishes between daily data cap plans, where the data allowance resets each day, and fixed data cap plans, where a specified amount of data is available for the entire validity period.
