BNESIM eSIM Data Plans for Japan

BNESIM does not provide a truly unlimited data eSIM plan for Japan. The only plan titled “Japan Unlimited 10 days” is capped at 3 GB per day, after which the speed drops to 1000 kbps, so high‑speed data is not unlimited.

Travelers who need more data can choose fixed‑data plans instead. For example, BNESIM offers a 100 GB plan valid for 30 days or for an unlimited period, each at a cost of about $46–$58 USD. These plans give a large, uninterrupted data allowance that may be more cost‑effective for most travelers.

BNESIM does not provide a Japan eSIM that includes a phone number or SMS capability. All plans sold by BNESIM for Japan are data‑only and do not support voice calls or text messaging.

Travelers can still use VoIP services—such as WhatsApp, Telegram, or iMessage—over the data connection for calls and messaging. However, some destinations may block or restrict specific apps or VoIP services, so it is advisable to verify that the applications you rely on are accessible in Japan before purchasing a plan.

BNESIM supplies plan options for travelers to Japan that include both single‑country offerings and multi‑country packages. In Japan’s realm, there are 15 distinct single‑country plans available, while 38 different multi‑country plans cover Japan as part of a broader regional or international bundle.

Across these offerings, the price per plan spans roughly $2.84 to $433.02, and the data caps range from 1 GB to 100 GB, reflecting choices from low‑usage daily or fixed‑data plans to higher‑capacity options suited to enterprise or long‑stay travelers. The single‑country set primarily consists of fixed‑data‑cap plans, whereas the multi‑country collection includes a mix of fixed caps and a handful of daily‑cap options, allowing travelers to pick a structure that best matches their usage pattern.
