Strong eSIM eSIM Data Plans for Japan

Strong eSIM does not provide any unlimited data eSIM plans for Japan. Instead, it offers fixed data plans that can be suitable for most travelers. For example, the Japan 50GB 30Days plan gives 50 GB of high‑speed data for 30 days, and the Japan 50GB 180Days plan offers the same data amount for 180 days. These fixed‑data alternatives may be more cost‑effective unless a traveler is an extremely heavy data user.

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 provides 40 single‑country plans and 52 multi‑country plans for Japan. The available options range in price from roughly $1.01 to $222.90, with data caps that span from 100 MB up to 50 GB; validity periods vary between one day and 365 days.
