Jetpac eSIM Data Plans for Japan

Jetpac does not provide a plan that gives an unlimited amount of high‑speed data for Japan. The plans that carry “Unlimited” in the name contain a fixed data allowance of 3GB per day, and after that limit the speed to 1000kbps. Travelers who need more data can choose Jetpac’s fixed‑data plans, such as the 40GB plan for 30 days or the 50GB plan for 365 days, which offer large data caps without the speed reduction that applies to the unlimited‑named plans.

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.
