Soovia eSIM does not provide an unlimited data eSIM for Japan. The available Japan plans have fixed data caps, such as 20GB for a 30‑day period, 20GB for 30 days with extended coverage, and 50GB for 30 days or 180 days. These fixed data plans give travelers a clear amount of high‑speed internet, and for most users they are more cost‑effective than paying for unlimited usage. If a visitor needs larger data allowances, the 50GB plans illustrate the maximum bundled option that Soovia offers for Japan.
