Kolet eSIM Data Plans for Japan

Kolet does not provide an unlimited data eSIM plan for Japan. The available plans are fixed‑data packages. For example, a 20GB plan valid for 30 days costs $32.99 USD, and a 10GB plan valid for 30 days is $21.99 USD. Choosing a fixed‑data plan can be more cost‑effective for most travelers unless you expect to use an extremely high amount of data.

Kolet does not offer eSIM plans for Japan that include a local phone number or SMS capability. All Kolet eSIMs available for Japan are data‑only, providing internet access without voice or messaging services tied to a mobile number.

Travelers who need to make calls or send texts can use popular VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection provided by Kolet’s eSIMs.

Kolet provides five single‑country data plans that cover Japan, as well as ten multi‑country plans that include Japan among other destinations. The plans range in price from $3.99 to $82.49 and offer between 1 GB and 20 GB of data, with validity periods that can be as short as 30 days or extend up to 365 days.
