FairPlay eSIM Data Plans for Japan

FairPlay offers unlimited data eSIM plans for Japan, all of which are available under the UNLIMITED OneWorld brand. The plans range from 1 day to 30 days, with prices starting at $11.70 USD for a single‑day plan and going up to $87.75 USD for a 30‑day plan. These unlimited plans use the 4G/LTE and 5G networks and allow tethering, but the provider notes that speeds may be throttled after heavy usage under a fair‑usage policy. Travelers who are concerned about potential speed restrictions should contact FairPlay directly to confirm the details of the fair‑usage policy and the typical amount of data that remains at normal speed.

FairPlay does not provide an eSIM for Japan that includes a local phone number or SMS capability. The provider only offers data‑only eSIM plans for Japanese travelers.

For voice and messaging, users can rely on popular VoIP applications such as WhatsApp, Telegram, or iMessage, which operate over the data connection and do not require a traditional phone number or SMS service.

FairPlay’s offering for Japan consists of 13 multi‑country plans. These plans are priced between $11.70 and $105.31 and deliver data caps ranging from 1 GB up to unlimited, depending on the validity period selected. Because there are no single‑country plans available for Japan, the focus is on these multi‑country options that can be activated on the eSIM and allow tethering, though speeds may be throttled in some cases.
