BNESIM eSIM Data Plans for Japan

BNESIM does not provide a truly unlimited data eSIM for Japan. All of their Japan‑specific plans have a fixed data allowance. For example, the “Surf 100 GB in Japan” plan offers 100GB of high‑speed data for an unlimited validity period, and the “Japan Unlimited 10 days” plan provides only 3GB per day for 10 days, after which the speed is reduced to 1000kbps. These options can be suitable for travelers who need a large amount of data without committing to a monthly contract, but they are not unlimited in the sense of offering data without caps. If a user requires more data or is a very heavy consumer, choosing a fixed data plan can be more cost‑effective than paying for a plan that would throttle speed or require frequent top‑ups.

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 offers 15 single‑country data plans that cover only Japan plus 42 multi‑country data plans that include Japan as part of their coverage. All plans are available in a range of data caps from 1 GB up to 100 GB, and their prices vary from about $2.87 to $230.71. Fixed‑data plans provide a set amount of data for the entire validity period, whereas daily‑cap plans restrict the amount of data you can use each day.
