BNESIM eSIM Data Plans for Japan

BNESIM does not provide a truly unlimited high‑speed data eSIM for Japan. The only plan that bears an “unlimited” name, “Japan Unlimited 10 days, ” actually caps usage at 3GB per day; after the limit is reached the speed is reduced to 1000kbps. For travelers who need higher data totals, BNESIM offers several fixed‑data options: a 100GB plan valid for 30 days, a 100GB plan with unlimited validity, a 50GB plan for 30 days, a 50GB plan with unlimited validity, and a 20GB plan for 30 days. Choosing a fixed data plan can be more economical unless a user expects to consume data at a very high rate for an extended period.

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.
