TripSIM eSIM Data Plans for Japan

TripSIM does not provide an unlimited data eSIM for Japan.
Instead they offer fixed data plans, such as their Japan eSIM – 50 GB plan valid for 100 days or the Japan eSIM – 30 GB plan valid for 60 days. These options give a large data allowance that is included in the price and must be used within the specified validity period. Choosing a fixed‑data plan can be more cost‑effective for most travelers unless they expect to consume data far beyond those thresholds.

TripSIM does not provide a Japan eSIM that includes a phone number or SMS capability. Only data‑only eSIM plans are offered for Japan.

Travelers can use VoIP applications such as WhatsApp, Telegram, and iMessage over the data connection, but some services may be blocked or restricted in Japan. It is advisable to check the accessibility of the apps you rely on before purchasing.

The service lists 10 single‑country plans and 5 multi‑country plans that include Japan. Many of the plans offer fixed data amounts while others provide daily data caps. The available options cover a price range from roughly $5 to $105 and data caps between 1 GB and 50 GB, with validity spans from 7 to 100 days.
