PuraSIM eSIM Data Plans for Japan

PuraSIM does not provide an unlimited data eSIM for Japan. Instead, PuraSIM offers fixed‑data plans that deliver a set amount of high‑speed data for a limited period. The largest plans available are the Japan 50GB 30Days plan at $47.99 USD and the Japan 50GB 180Days plan at $78.49 USD, both providing 50 GB of data for 30 or 180 days respectively. A smaller option is the Japan 20GB 30Days plan for $24.99 USD.

Choosing a fixed data plan is generally more cost‑effective for most travelers, as the cost per GB is lower than what would be incurred by constantly topping up a pay‑as‑you‑go balance. Travelers who anticipate very heavy data usage might find it beneficial to consider a higher‑capacity plan or a different provider that offers larger data bundles or unlimited usage, depending on their needs.

PuraSIM does not provide eSIM plans for Japan that include a phone number or SMS capability. Only data‑only eSIM plans are offered for this destination.

Travelers can use VoIP applications such as WhatsApp, Telegram, and iMessage over the data connection for calls and messaging. However, some destinations may block or restrict access to specific apps or VoIP services, so it is advisable to verify that the apps you rely on are accessible in Japan before purchasing a plan.

PuraSIM provides a total of 20 single‑country data plans and 83 multi‑country data plans that can be used while traveling in Japan. The plans span a price range from $0.59 up to $261.49, with data caps between 100 MB and 50 GB and validity periods from 3 days to 365 days. Of the available plans, 49 operate with a daily data cap and 54 offer a fixed data amount, giving users flexibility between recurring daily limits and a single, larger data allocation for the entire validity period.
