Truphone eSIM Data Plans for Japan

Truphone does not provide an unlimited data eSIM plan for use in Japan. The available offerings are fixed‑data packages that specify a maximum data cap for the duration of the validity period.

Travelers who need a substantial amount of data can consider Truphone’s larger plans, such as the 20GB 30‑day local eSIM for $58.11 USD or the 10GB 30‑day local eSIM for $40.68 USD. These fixed‑data options may be more cost‑effective for most users unless the traveler is a very heavy data consumer who would benefit from a different vendor’s unlimited plan.

Truphone does not provide Japan eSIM plans that include a local phone number or SMS capability. All available Japan eSIM options from Truphone are data‑only. Travelers can still use VoIP services such as WhatsApp, Telegram, or iMessage over the data connection for voice and messaging needs.

Truphone currently offers 5 single-country data plans specifically for Japan, alongside 6 multi-country plans that include Japan as part of their coverage. These plans range in price from approximately $5.67 to $56.70 and offer data allowances between 1GB and 20GB. Plan validity periods vary from 1 to 30 days. Some plans provide a fixed data amount, while others may offer data usage over a set number of days.
