eSIMX eSIM Data Plans for Japan

eSIMX does not offer an unlimited data eSIM plan for Japan.
Instead, eSIMX provides fixed data plans that cover Japan, such as the Global 100GB 30Days With Calls plan, the Global 50GB 30Days With Calls plan, and the Japan 30GB 30Days plan. These plans give large data allowances at a set price, which can be more cost‑effective for most travelers unless the user is an extremely heavy data consumer.

eSIMX provides Japan eSIM plans that include a phone number and SMS capabilities. The available options are 20GB, 50GB, and 100GB data plans, each valid for 30 days and priced at $33.80, $64.80, and $85.80 USD respectively. These plans use a phone number with the dialing code +376, allowing both inbound and outbound voice calls and inbound and outbound SMS messages. Because the number is not a local Japanese number, users should check with eSIMX to confirm call and messaging functionality for their specific needs.

eSIMX provides 16 single‑country data plans that cover Japan only, and 27 multi‑country plans in which Japan is one of the included destinations. The available packages span a price range from roughly $2.80 to $85.80 USD and include data allowances between 1 GB and 100 GB over validity periods of 1 to 30 days. Among the catalog, 12 plans are structured with a daily data cap—offering a set amount of data per day—while 31 plans provide a fixed data amount that remains available for the full validity period.
