Jetpac eSIM Data Plans for Japan

Jetpac does not provide a truly unlimited data eSIM for Japan. All plans labeled “Unlimited” give a daily allowance of 3GB and apply a reduced speed of 1024kbps once that daily limit is reached. For travelers who need more than 3GB per day, Jetpac offers fixed‑data plans such as the 40GB plan for 30 days and the 30GB plan for 30 days, which may be more economical for moderate or heavy data usage.

Jetpac does not provide eSIM plans for Japan that include a local phone number or SMS capability. All Jetpac Japan plans are data‑only, meaning they offer high‑speed internet access without voice or text services. Travelers who need voice or messaging can use popular VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection.

Jetpac supplies a total of 22 single‑country data plans and 34 multi‑country plans that are valid in Japan. The single‑country offerings feature fixed data caps that range from 1 GB to 50 GB, while the multi‑country options may use either a fixed data amount or a daily data cap (about 0.5 GB to 5 GB per day). The pricing for these plans spans roughly $4 to $249 USD, giving customers a broad selection of data volumes and validity periods without specifically binding the answer to the question wording.
