Strong eSIM eSIM Data Plans for Japan

Strong eSIM does not provide an unlimited data eSIM plan for Japan. Travelers can choose from fixed data allowances instead, such as the Japan 50GB 30Days plan at $55.90 and the Japan 20GB 30Days plan at $26.90. These plans include tethering and 5G coverage in Japan and can be a more cost‑effective option unless a user requires a very high amount of data.

Strong eSIM does not provide a Japan eSIM that includes a phone number or SMS capability. Only data‑only eSIM plans are offered, so the service cannot receive or send text messages or make calls using a local number. Travelers can instead use VoIP applications such as WhatsApp, Telegram or iMessage over the data connection to make voice calls and send messages without a traditional phone number.

Strong eSIM lists 42 single‑country data plans and 58 multi‑country plans in its catalog. The data provided does not break out the numbers by individual country, so the precise count of Japan‑only or Japan‑included plans is not stated in the available information.
