BNESIM eSIM Data Plans for Japan

BNESIM does not offer a true unlimited high‑speed data eSIM for Japan. The product named “Japan Unlimited 10 days” limits usage to 3GB per day; once that threshold is exceeded the speed is throttled to 1000 kbps. For travelers needing larger data allowances without a daily cap, BNESIM provides fixed data plans such as the 100 GB–validity options, which are available for 30 days or indefinitely. These plans deliver 5G speeds throughout Japan and can be more economical for users who consume large amounts of data but do not require a continuous unlimited data flow.

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 provides 14 single‑country data plans that are specifically for Japan, and an additional 38 multi‑country plans that include Japan as part of their coverage. The single‑country options feature a variety of fixed data caps ranging from 1 GB up to 100 GB, with prices spanning from about $3.41 to $432.94. The multi‑country plans cover a similar data range and price spectrum; many of them offer daily data caps in addition to fixed amounts, allowing users to switch between daily limits and larger data bundles depending on their usage. Overall, customers can choose between a compact selection of Japan‑only plans or a broad set of international‑plus‑Japan packages to suit different budgets and data needs.
