ID verification

Japan Wireless: Not required

Refund policy

abesteSIM: Full/partial refund or replacement if the eSIM fails to install/activate/work due to a fault on abesteSIM's or the carrier's side, or works only intermittently. A 2.5 SGD or 10% (whichever is higher) processing fee applies for device-incompatibility/carrier-lock refunds. No refund for wrong purchases, an expired activation window, expired unused data, wrong checkout email, or once the eSIM has been installed.

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

Validity starts

abesteSIM: Most plans start when the eSIM first connects to a supported network and begins using data; some instead use a fixed start date or activate on installation — stated per plan on its own product page (per their FAQ).

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

abesteSIM: Some unlimited plans apply a fair-use policy after a high-speed threshold; others state a fixed speed cap (e.g. 5/10/20 Mbps) instead — varies per plan, check the product description (per their FAQ).

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

abesteSIM: No — abesteSIM does not currently support topping up an installed eSIM; buy a new plan once the existing allowance ends (per their FAQ).

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

Lost device / reinstalling

abesteSIM: A lost/misplaced QR code can be resent by contacting support (email or live chat) before installation, when eligible. Once installed, an eSIM is bonded to that device and can't be transferred or reissued — contact support about a replacement rather than a reissue.

Japan Wireless: A Japan Wireless eSIM can only be installed once -- if you delete it from your device after installation you cannot reinstall it, and must contact Japan Wireless customer support for help.

Billing currency

abesteSIM: Users in Canada, Europe, the UK, Hong Kong, Japan, Taiwan, and the USA can pay in their local currencies; users in other regions are billed in SGD.

Japan Wireless: Checkout lets you choose your billing currency (USD, EUR, GBP, AUD, CAD, JPY, KRW and more) via a currency selector.
