BNESIM eSIM Data Plans for Japan

BNESIM does not provide a truly unlimited high‑speed data eSIM for Japan. The plan named “Japan Unlimited 10 days” offers 3 GB of high‑speed data per day, after which the connection is throttled to 1000 kbps; the name “Unlimited” refers only to the daily allotment, not to an unlimited data allowance.

Travelers who need a guaranteed amount of data can select one of BNESIM’s fixed‑data options. For example, a 100 GB plan is available for 30 days at $46.35 USD, and a 50 GB plan for 30 days costs $23.17 USD. These plans allow the full data allowance at standard 5G speeds until the quota is reached, after which the reduced‑speed provision in the “Japan Unlimited” plan would apply if the user continued to consume data.

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 currently offers 14 single‑country data plans and 30 multi‑country data plans for use in Japan. These plans span a price range from about $3.47 to $258.90 and provide data caps between 1 GB and 100 GB, with validity periods ranging from no expiry up to 30 days. Among the options, plans include one daily‑data‑cap model and 43 fixed‑data‑cap models, giving travelers the choice between a daily limit and a total data allotment.
