Kolet eSIM Data Plans for Japan

Kolet does not provide an unlimited data eSIM plan for Japan. Travelers who need large amounts of data can choose from Kolet’s fixed data plans; for example, a 20GB plan valid for 30 days costs $33.99 USD, and a 20GB plan valid for 365 days is $82.99 USD. Selecting a fixed data plan may be more cost‑effective for most users, unless the traveler's usage exceeds these limits by a substantial margin.

Kolet does not provide an eSIM plan for Japan that includes a phone number or SMS capability. Their Japan offerings are data‑only, so no voice or text services are available through a local number. Travelers wishing to make voice calls or send messages can use VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection. However, some destinations may restrict access to specific apps or services, so it is advisable to verify that the apps you need are available in Japan before purchasing.

Kolet offers five single‑country data plans for Japan and ten multi‑country plans that include Japan as one of the covered destinations. The single‑country plans vary from a 1 GB package to a 20 GB package and are priced between $3.99 and $82.49 depending on validity and data amount, with options that are either fixed data bundles or daily data caps for shorter terms. The multi‑country plans cover Japan together with other Asian, Latin American, or European countries, and feature similar data caps ranging from 1 GB to 20 GB, with prices that also fall within the $3.99 to $82.49 range.
