The unlimited plans do not have a fixed data cap, but the provider notes that speed may be throttled after heavy usage. Under a Fair Usage Policy, speeds may be reduced once a usage threshold is reached. Travelers who are concerned about potential speed restrictions should contact Truely to confirm whether the Fair Usage Policy applies and to learn the typical amount of data available at normal speed.

Does Truely offer Japan eSIM with phone number and SMS?

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.

How many data plans does Truely offer for Japan?

Truely lists 17 single‑country plans that cover only Japan and 17 multi‑country plans that include Japan in addition to other destinations.
