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 sells a range of Japan eSIM plans that include a phone number and allow inbound SMS. Prices start at $4.00 USD for a 1GB data package valid for 7 days and rise to about $67.00 USD for a 20GB data package valid for 30 days, with validity periods available in 7‑ to 30‑day increments. The plans use dialing code +1, meaning the assigned number is not a local Japanese number. Calls can be received and made (inbound and outbound voice), and SMS can be received only; sending SMS is not supported. Travelers are encouraged to contact GlobaleSIM directly to verify the dialing code and any specific requirements.

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.
