Frequently Asked Questions

Does Truely offer unlimited data eSIM for Japan?

Truely does offer unlimited‑data eSIM plans for Japan. The plans vary in validity from 1 day to 30 days and the price ranges from $5.52 for the 1‑day option to $74.93 for the 30‑day option. All of the unlimited plans allow tethering and the data is available on 3G, 4G and 5G networks. Because a Fair Usage Policy applies, high‑volume users may experience speed throttling after extended use at normal speed. Travelers who are concerned about potential reductions should contact Truely directly to confirm how the policy is applied and what typical bandwidth remains at the normal speed tier.

Does Truely offer Japan eSIM with phone number and SMS?

Truely does not provide an eSIM for Japan that includes a phone number or SMS capability. The provider offers only data‑only plans, so travelers can still use VoIP and messaging apps such as WhatsApp, Telegram, and iMessage over the data connection for voice and text communications.

How many data plans does Truely offer for Japan?

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.
