Keep On Roaming eSIM Data Plans for Japan

Keep On Roaming does not provide a plan that offers truly unlimited high‑speed data in Japan. All plans with “Unlimited” in the name provide a fixed allowance of 1 GB per day, and after that amount the speed is reduced. Travelers who need more data can choose from several fixed‑data options, such as the 20 GB 30 days plan at $22.00 USD, the 10 GB 30 days plan at $19.00 USD, or the 5 GB 30 days plan at $15.00 USD. These alternatives may be more cost‑effective unless a user requires an extremely large data quota.

Keep On Roaming does not offer a Japan eSIM that provides a phone number or SMS capability. The plans available for Japan are data‑only, so subscribers receive only a data allowance. Any voice or text communication must be done through internet‑based applications such as WhatsApp, Telegram or iMessage, which work over the data connection.

Keep On Roaming offers 12 single‑country plans and 11 multi‑country plans that cover Japan. Prices span from $7.00 to $148.00, with data caps ranging from 1 GB to 20 GB and validity periods of 1 to 30 days. Plans are available in both fixed data amounts and daily data caps, allowing travelers to choose either a specific total data allotment or a daily usage limit that suits their travel style.
