Kolet eSIM Data Plans for Japan

Kolet does not provide an unlimited data eSIM plan for Japan. Instead, the provider offers fixed data plans, such as a 20GB plan that is valid for 30 days and costs $32.99 USD, or a 10GB plan that is valid for 30 days and costs $21.99 USD. These examples illustrate the type of high‑data‑allowance options that are available, but they represent only a portion of the full range of plans Kolet offers. Choosing a fixed‑data plan can be more cost‑effective unless a traveler is an extremely heavy data consumer who requires continuous, unlimited data usage.

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.
