Jetpac eSIM Data Plans for Japan

Jetpac does not offer a truly unlimited high‑speed data plan for Japan. All plans that use the word “Unlimited” in the name actually provide a fixed data allowance of 3 GB per day and apply a reduced speed of 1000 kbps once the daily limit is reached, so long‑term usage is throttled.

Travelers can choose from fixed‑data plans such as the Japan 40 GB plan for 30 days at $34.99 USD or the Japan 30 GB plan at $29.99 USD. These provide a larger, non‑throttled data allowance and can be more cost‑effective for most users who do not need unbounded high‑speed data.

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 offers a mix of single‑country and multi‑country data plans that cover Japan. The directory lists 23 single‑country offerings and 26 multi‑country packages that include Japan. Among the total plans, 14 are priced by daily data cap and 35 by fixed data amount, giving travelers a range of options: prices vary from about USD 4.00 up to USD 249.00, data caps run from 1 GB to 50 GB and validity periods cover 1 to 365 days. The single‑country plans give you a dedicated data allowance for Japan alone, while the multi‑country packages divide data across several destinations, some of which include the Japanese market.
