eSIMX eSIM Data Plans for Japan

eSIMX does not offer any unlimited data plan for Japan; all available plans list a specific data allowance. The provider’s product line for Japan includes fixed‑data options such as the Japan 30GB 7Days plan priced at $18.80 USD, the Japan 30GB 30Days plan at $21.80 USD, and a broader Global 100GB 30Days plan that covers Japan and over 107 other countries for $85.80 USD.

Choosing a fixed‑data plan can be more cost‑effective for most travelers, and the larger data bundles available can suit moderate to heavy usage. However, if a user expects to consume a very large amount of data, they may need to evaluate the plan’s data limits against their anticipated needs.

eSIMX provides Japan eSIM plans that include a phone number and SMS capability. Three options are available: Global 20GB 30Days With Calls, Global 50GB 30Days With Calls, and Global 100GB 30Days With Calls, priced from $33.80 USD to $85.80 USD and valid for 30 days. Each plan uses a phone number with dialing code 376, which is not a local Japanese number, and supports inbound and outbound voice calls as well as inbound and outbound SMS. Travelers who need a specific set of voice or SMS features should confirm the details directly with eSIMX.

eSIMX provides 16 single‑country plans and 27 multi‑country plans for travelers in Japan. The available plans span a price range from USD 2.80 to USD 85.80. Data caps vary widely, from 1 GB up to 100 GB, depending on whether a plan offers a fixed data amount or a daily data cap. For fixed data–cap options there are 31 distinct choices, while 12 plans use a daily data cap model. These figures give a broad view of the options a user can compare on eSIMDB.
