Truphone eSIM Data Plans for Japan

Truphone does not offer unlimited data eSIM plans for Japan.
Instead, they provide fixed‑data options that may suit most travelers. For example, a 20 GB plan is available for 30 days at a price of $58.17 USD, while a 10 GB plan can be bought for $40.72 USD and a 5 GB plan for $20.94 USD, all for 30 days of local use. Selecting a fixed data plan is typically more cost effective, unless a user requires exceptionally high data volumes.

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.
