GlobaleSIM eSIM Data Plans for Japan

GlobaleSIM does not provide an unlimited data eSIM plan for Japan. All plans list a fixed data cap, such as a 20 GB or 15 GB allowance that is valid for 30 days.

For travelers who need a larger data allowance, GlobaleSIM offers fixed plans: a 20 GB plan for 30 days costs $27.00 USD, and a 15 GB plan for 30 days costs $25.00 USD. Choosing a fixed data plan can be more cost‑effective unless the user is an extremely heavy data consumer.

GlobaleSIM provides a range of eSIM plans for Japan that include a phone number and the ability to receive SMS. Prices vary from $4.00 USD for a 1GB, 7‑day plan to $67.00 USD for a 20GB, 30‑day plan. Validity periods offered span from 7 days up to 30 days, allowing travelers to choose a plan that suits their stay.

All Japan eSIMs use the dialing code +1, meaning the phone number is a US number that can be used while in Japan. Calls can be received and sent, and SMS messages can be received; outbound SMS is not supported. For specific details such as local number options or additional services, travelers should contact GlobaleSIM directly.

GlobaleSIM offers six single‑country plans for Japan and 18 multi‑country plans that include Japan. The plans are priced from four to sixty‑seven dollars, feature data caps between one and twenty gigabytes, and remain valid for seven to thirty days. Each plan provides a fixed data amount rather than a daily data cap.
