eSIM Cards for Japan FAQ

Does eSIM Cards offer unlimited data eSIM for Japan?

eSIM Cards does not offer an unlimited‑data option for Japan. Travelers looking for high volumes of data instead choose one of several fixed‑data plans. For instance, the Japan 300GB Travel Plan provides 300 GB of data over 15 days, and the Japan 50GB Travel Plan supplies 50 GB for 30 days. These fixed plans are typically more cost‑effective unless a user requires very large data consumption, in which case a larger plan would be a better fit.

Does eSIM Cards offer Japan eSIM with phone number and SMS?

eSIM Cards does not provide a Japan eSIM that includes a phone number or SMS capability. The provider’s offerings for Japan are limited to data‑only plans.

Travelers can still use popular VoIP services such as WhatsApp, Telegram, and iMessage over the data connection, but those apps must be verified for availability in Japan before purchasing.

eSIM Cards offers 8 single‑country plans and 2 multi‑country plans for Japan, a total of 10 data packages. Prices run from about $3.93 to $69.09 USD, while data caps vary between 3 GB and 300 GB. Validity periods range from five to thirty days, and several plans include tethering permission.
