BNESIM eSIM Data Plans for Japan

BNESIM does not provide a truly unlimited data eSIM for Japan. The only plan that carries “Unlimited” in its name gives 3GB per day and drops the speed to 1000kbps once the daily limit is reached, so the data is not unlimited.

Travelers can instead choose from fixed‑data plans that offer large allowances. For example, BNESIM sells a 100GB plan for 30 days and a 50GB plan for 30 days, as well as a 20GB plan for 30 days. These plans give high‑speed data until the specified amount is used, which is typically more cost‑effective for most visitors.

BNESIM does not provide a Japan eSIM that includes a local phone number or SMS capability. All plans offered by BNESIM for Japan are data‑only, meaning they give you high‑speed internet access but no voice or text services. You can still stay connected using popular VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection, which allow voice and messaging without a traditional phone number.

BNESIM provides 14 single‑country data plans and 30 multi‑country options that include Japan. The plans cover a price range from $3.52 to $262.73 and offer data caps between 1 GB and 100 GB, with validity periods that vary from no expiry to 30 days. Most plans use a fixed data cap, giving a set amount of data for the entire validity period, while one plan offers a daily data cap that limits usage each day.
