Earth Esim eSIM Data Plans for Japan

Earth Esim does not provide an unlimited data eSIM for Japan. Travelers must choose from fixed data plans. For example, a 50GB plan is available for 30 days at $22.00 USD, and a 20GB plan for 30 days costs $16.50 USD. Both plans include tethering and use 5G networks within Japan.

Choosing a fixed data package can be more economical unless the user requires very high data usage; an unlimited offering would eliminate caps but is currently not offered by Earth Esim for Japan.

Earth Esim does not provide a phone number or SMS capability for its Japan eSIM plans. The provider only offers data‑only eSIMs, so travelers cannot receive traditional phone calls or text messages through the device’s native phone function.

Travelers who need to communicate while in Japan can still use popular VoIP apps such as WhatsApp, Telegram, and iMessage over the data connection, which allow voice calls and messaging without requiring a local phone number or SMS service. The plans are available exclusively for high‑speed internet use.

Earth Esim provides 11 single‑country plans for Japan and 21 multi‑country plans that include Japan in their coverage. Some of the plans offer a fixed data amount for the entire validity, while others limit the data used each day during the subscription period. Prices range from $0.79 to $140.00, and data caps vary between 500 MB and 50 GB. Validity periods span anywhere from 1 day up to 180 days, and a number of plans allow tethering by connected devices.
