Japan Wireless: Not required

Refund policy

BNESIM: Refund requests must be made within 14 days of purchase and are denied once over 10% of the plan's data has been used; approved refunds go to BNE Wallet credit (24h) or the original payment method (up to 3 business days).

Japan Wireless: eSIM orders can't be cancelled or refunded once dispatched (erroneous shipments excepted); pocket WiFi rentals cancel free before shipment.

Validity starts

BNESIM: Data validity starts counting down as soon as a plan is purchased by default; BNESIM also lets you schedule activation for a specific future day instead. Once installed, the eSIM begins working within about a minute of connecting to a local network.

Japan Wireless: Validity starts when the eSIM is actually activated, not at purchase, counted in 24-hour days; it must be activated within 30 days of purchase or it expires.

Fair-use limit

BNESIM: Unlimited-data plans may be suspended if daily usage reaches 5GB or monthly usage reaches 100GB; BNESIM reserves the right to limit speed for very high network use.

Japan Wireless: 4G Unlimited (DOCOMO) throttles to 256kbps after 3GB/day, resetting at midnight JST; 5G Unlimited (KDDI) has a general fair-use policy with no fixed daily cap stated.

Top-ups & rollover

BNESIM: Top up via the BNESIM eSIM app: open My eSIMs, pick the eSIM to recharge, then choose a country and data plan; no reinstall needed.

Japan Wireless: Existing eSIMs cannot be topped up; extra data requires purchasing a new/additional data plan, per Japan Wireless's own FAQ.
