eSIM4Travel eSIM Data Plans for Japan

eSIM4Travel does not provide an unlimited data eSIM plan for Japan. Instead, the provider offers fixed data plans that cover the entire duration of a trip. For example, the Japan (KDDI) – 30GB/30Days plan costs $32.72 USD and the Japan (KDDI) – 20GB/30Days plan costs $22.18 USD. These options allow travelers to choose a data allowance that fits their needs; they can be more cost‑effective for most users unless one expects to use an extremely high volume of data.
