eSIM Prime eSIM Data Plans for Japan

eSIM Prime does not currently offer an unlimited data eSIM for Japan. Travelers who need more data than the available fixed‑data plans can choose from a range of options, such as a 20GB plan valid for 30 days costing $30.99 USD, or a 10GB plan for the same duration priced at $18.99 USD. These larger allowance plans provide a greater volume of data and can be more cost‑effective for most users compared to purchasing multiple smaller packages, unless the user is an extremely heavy data consumer who would benefit from a true unlimited plan.

eSIM Prime does not provide a Japan eSIM that includes a phone number or SMS capability. All the plans it offers for Japan are data‑only, so users cannot receive or place calls or send text messages directly through the eSIM. Travelers who need to communicate while abroad can still use popular VoIP applications such as WhatsApp, Telegram or iMessage, which work over the data connection and allow voice calls and messaging without a local phone number or SMS service.

eSIM Prime provides five single‑country data plans when you travel to Japan. The available plans span a price range from $2.99 to $30.99, with data caps from 1 GB up to 20 GB and validity periods of 7 to 30 days. Some of these plans allow tethering, giving additional flexibility for device connectivity.
