BNESIM eSIM Data Plans for Japan

BNESIM does not provide a true unlimited data eSIM for Japan; the only plan labeled “Japan Unlimited” is actually limited to 3 GB per day and reduces speed to 1000 kbps once that daily cap is reached. This plan is therefore not unlimited in the sense of providing high‑speed data without limits.

Instead, BNESIM offers a range of fixed‑data options for travelers. For example, a 100 GB plan is available for 30 days at $46.22 USD, and a 20 GB plan is available for 30 days at $11.55 USD. These fixed plans can be more cost‑effective for most users, especially those who do not need extremely heavy data usage.

BNESIM does not provide Japan eSIM plans that include a phone number or SMS capability. All plans available from BNESIM for Japan are data‑only, with no inbound or outbound voice or text services. Because of this, travelers cannot receive or make traditional phone calls or SMS messages through BNESIM’s eSIMs.

Travelers who need voice or messaging while in Japan can use popular VoIP applications such as WhatsApp, Telegram, or iMessage, which work over the data connection provided by the eSIM. These apps enable both calls and messages without requiring a local phone number.

BNESIM provides 14 single‑country data plans that are valid for Japan, while it also offers 30 multi‑country plans that include Japan in their coverage. The available plans span a price range from about $3.46 to $258.17 and data caps from 1 GB up to 100 GB, with most options being fixed‑data packages and only a single daily‑cap plan in the catalogue.
