Jetpac eSIM Data Plans for Japan

Jetpac does not provide a truly unlimited data eSIM for Japan. The plans that carry “Unlimited” in their name actually grant 3GB of high‑speed data per day; once that amount is reached the speed is throttled to 1000kbps. This is a fixed data plan, not an unlimited one.

Travelers who need more data can choose from Jetpac’s fixed data plans that offer larger allowances, such as the Japan 40GB plan valid for 30 days or the Japan 30GB plan also valid for 30 days. These plans give a larger amount of high‑speed data without the daily limit and can be more cost‑effective for heavy data users.

Jetpac does not provide a phone number or SMS capability on its Japan eSIM; the provider only offers a data‑only plan for that destination. Travelers can use VoIP applications such as WhatsApp, Telegram, and iMessage over the data connection to make calls and send messages, but they should verify that these services are accessible in Japan before purchasing, as some destinations may block or restrict specific apps.

Jetpac supplies 24 single-country plans that cover Japan, along with 33 multi-country plans that include Japan among their destinations, giving travelers a total of 57 distinct data options. The plans are divided into two main types: fixed data cap plans that offer a set amount of data for the life of the package, and daily data cap plans that reset the data allowance every 24 hours. Prices for Japan‑specific packages start around USD 5 and can rise to roughly USD 249, while data amounts range from 1 GB up to 50 GB depending on the chosen plan and its validity period, which can span from a single day to a full year.
