Truely eSIM Data Plans for Japan

Truely provides several unlimited data eSIM plans for Japan that work on the country’s 3G, 4G, and 5G networks and allow tethering. Validity ranges from 1 day to 30 days, with prices from $5.52 USD for the 1‑day plan up to $74.93 USD for the 30‑day plan. Because the plans are unlimited, Truely may throttle speed after heavy use under a Fair Usage Policy; travelers who are concerned about speed reductions are advised to contact Truely directly to confirm whether a Fair Usage Policy applies and the typical amount of data that remains available at normal speed.

Truely does not provide a Japan eSIM that includes a phone number or SMS capability. The provider only offers data‑only plans for travelers in Japan. If you need to make calls or send messages, you can use popular VoIP applications such as WhatsApp, Telegram or iMessage over the data connection.

Truely offers eight single‑country data plans for Japan and an equal number – eight – of multi‑country plans that include Japan. Some plans provide a fixed amount of data for the entire validity period, while others give a daily data cap that renews each day. Across all Japan‑specific options the price range is approximately $5.52 to $89.91, and the data allowance spans from a few gigabytes to unlimited.
