Kolet eSIM Data Plans for Japan

Kolet does not offer an unlimited data eSIM plan for Japan. Travelers can instead choose from fixed‑data options, such as a 20GB plan for 30 days at $41.99 USD or a 10GB plan for 30 days at $20.99 USD, both available on 5G networks. Selecting a fixed data plan can be more cost‑effective unless a user requires very high overall data usage.

Kolet does not provide eSIM plans for Japan that include a phone number or SMS capability. Customers who choose Kolet can only purchase data‑only eSIMs and will have no inbound or outbound voice or text services.

Because no phone number is provided, travelers can still use popular VoIP applications such as WhatsApp, Telegram and iMessage over the data connection for voice and messaging needs. These apps do not require a local phone number or SMS support.

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.
