Keep On Roaming eSIM Data Plans for Japan

Keep On Roaming does not offer a plan with unlimited high‑speed data for Japan. All plans that include “Unlimited” in their name are capped at 1GB of data (or 1GB per day for multi‑day options). After the cap is reached, the remaining data is throttled, so the speed is reduced, but the plan is not truly unlimited.

If you need more data, Keep On Roaming provides fixed‑data eSIMs for Japan. For example, a 20GB 30‑day plan costs $22.00 USD, a 10GB 30‑day plan costs $19.00 USD, and a 5GB 30‑day plan is available for $15.00 USD. These options may be more cost‑effective for travelers who anticipate higher data usage over longer stays.

Keep On Roaming does not provide Japan eSIM plans that include a phone number or SMS capability. The provider offers only data‑only eSIMs for Japan.

Users who need to make calls or send messages can use popular VoIP applications such as WhatsApp, Telegram, or iMessage, which operate over a data connection without requiring a local phone number or SMS service.

Keep On Roaming provides both single‑country and multi‑country options that include Japan. For single‑country plans a total of 12 are offered, while 11 plans that cover Japan as part of a broader regional itinerary are also available. The plans are divided into fixed data‑cap packages, where a set amount of data (between 1 GB and 20 GB) is provided for the plan’s validity period, and daily‑cap packages that limit data use each day of the validity (which can add up to the total cap over the period). Prices across all Japan‑inclusive plans range from roughly $7.00 to $148.00, giving customers a broad range of data limits and price points to choose from.
