PuraSIM eSIM Data Plans for Japan

PuraSIM does not provide any unlimited data eSIM plans for Japan. All of its Japan‑specific offerings have defined data caps, the largest being the Japan 50GB 30Days plan, which supplies 50GB of high‑speed data for 30 days.

Travelers who need substantial data can choose from PuraSIM’s fixed data plans. For example, the Japan 50GB 30Days plan costs $47.99 USD and delivers 50GB of 5G data for a month, while the Japan 20GB 30Days plan is $24.99 USD and offers 20GB of 5G data for the same period. These fixed‑cap options may be more cost‑effective for most users, unless an exceptionally heavy data consumer requires an unlimited service.

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.
